DellInspiron9400

Issues/Solutions with Lucid (alpha 3) x86-32

  • No proper suspend (X has to be restarted after wakeup using Alt+SysRq+K)

  • PCM and Master audio channels are interchanged and have been since Karmic. This time it needed more tweaking, at least for me. First, open /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf. Change volume=merge to volume=ignore for the LFE, Master and Hardware Master sections. Second, open /etc/pulse/default.pa and add control=PCM to the end of the line load-module module-alsa-sink. So the entire line is now:

    load-module module-alsa-sink control=PCM

  • The proprietary nvidia drivers are now functional (as of version 195 i believe). But now it's broken again as of kernel 2.6.32-15 Sad :(

  • PC speaker is now off by default I've heard?

Issues/Solutions with Karmic x86-32 (and possibly x86-64 as well)

  • The standard volume control only affects the treble speakers. The woofer is set to max with no way to lower it.
    • Workaround: Open /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf and change the LFE, Master and Hardware Master elements. Change 'volume = merge' to 'volume = ignore'. Now run alsamixer from a terminal and set Master and LFE to 100%. Volume hotkeys will now control PCM volume only, which is what you'll want.

  • I recommend that you turn off the noisy PC speaker (see Jaunty issues on the bottom of this page)

Issues with Previous Releases

Issues/Solutions with Jaunty x86-64

  • On shutdown, displays shutdown splash screen and then displays black screen with blinking cursor and fails to power-off. Appears to be related to the issues discussed in this Ubuntu forum thread. Bug# 355054

  • Blank screen on resume from suspend.
  • CPUs locked at max. frequency after resume from hibernate.

Issues/Solutions with Jaunty x86-32

  • Very loud PC-Speaker, and there is no way to lower the volume. To turn it off type the following into a terminal window:
    sudo rmmod pcspkr
    This will last until the next reboot. To disable it completely add the following line to /etc/modprobe.d/blacklist.conf:
    blacklist pcspkr

Issues/Solutions with Ibex x86-64

  • Problem: Media buttons (on front of laptop); Fn + PageUp (increase volume); and Fn + PageDn (decrease volume) have no affect on volume and media applications. (These automatically worked on previous releases.) Solution: Reset in System > Preferences > Keyboard Shortcuts --TylerKinkade

  • Nvidia Card not utilized. 3D acceleration and desktop effects not functioning.
    • Hardware Drivers will usally automatically detect the hardware and offer the right driver.
    • If Hardware Drivers does not automatically open, go to System > Hardware Drivers.

    • Click on appropriate graphics driver.
    • Click "Activate".
    • After download and installation, reboot computer.
    • -- D

Issues/Solutions with Gutsy i386

  • No virtual terminals (Ctrl + Alt + F1-F6)

    See this page and this thread for more information. The following is my post from the launchpad page. This is how I got my Dell Inspiron E1705/9400 with ATI Mobility Radeon X1400 working: sudo nano /etc/initramfs-tools/modules Add the following two lines to the bottom of the file:

     fbcon
     vga16fb
    sudo update-initramfs -u sudo nano /etc/modprobe.d/blacklist-framebuffer Change the line "blacklist vga16fb" to "#blacklist vga16fb" The only kernel parameters I have in menu.lst are "quiet splash" (the default)

    Reboot and all the virtual terminals should work. --AlexStrabala

  • The PC Speaker is very loud, and there is no way to lower the volume.I have seen Windows users complaining about this as well, so it may be a hardware design issue. To disable the pcspkr module loading on bootup simply add the following line to /etc/modprobe.d/blacklist

    to the end of the file. --AlexStrabala

     blacklist pcspkr
  • Keyboard and mouse freeze sometimes when waking up from suspend. Solution here: http://ubuntuforums.org/showpost.php?p=2690982&postcount=14 --AlexStrabala

  • Bluetooth won't connect or simply doesn't work. Install the bluez-gnome and gnome-vfs-obexftp packages and restart your computer. There's more about bluetooth further down this page if you still have problems. --AlexStrabala

  • Odd behavior of volume buttons. After a fresh install, they seem to only control the treble of songs. To fix this, run the following command and restart your computer:
     echo "options snd-hda-intel model=ref" | sudo tee -a /etc/modprobe.d/alsa-base
  • Right Alt key doesn't work out of the box. Solution: Go to System, Preferences, Keyboard. In the "Layout Options" tab, in the "Third Level Choosers" section, uncheck "Press Right Alt key to choose 3rd level." Also, in the "Alt/Win Key Behavior" section, select "Meta is mapped to the Win-keys."
  • Horizontal scrolling in firefox functions as back/forward. To fix this, type "about:config" in the address bar. Then type "mousewheel.horizscroll.withnokey" into the filter box. Set "mousewheel.horizscroll.withnokey.action" to "0" and "mousewheel.horizscroll.withnokey.sysnumlines" to "true".

Issues/Solutions with Feisty x86-64

In order to enter the commands on that wiki page switch to a virtual terminal after the black screen using Ctrl+Alt+F1.

  • ATI Cards: Laptop does not resume from suspend. Solution: Open /etc/default/acpi-support: sudo gedit /etc/default/acpi-support. In this file, change the line "POST_VIDEO=true" to read "POST_VIDEO=" You should now be able to suspend and resume without issue. I do not know if you have to restart your computer for the setting to take effect. --AlexStrabala

Issues/Solutions with Edgy x86-32

Note: Do not add the notsc kernel option mentioned in the x86-64 sections below. It will create a kernel panic with a x86-32 kernel. -- SridharDhanapalan

Note: Issues relating to the Core 2 Duo CPU and associated hardware are chronicled here.

  • By default, the GRUB bootloader installs to the MBR (master boot record). Installing in this fashion removes access to the built-in MediaDirect OS, which is located on a secret partition (not accessible by Linux or Windows) at the end of the drive.

    • Instructions to have GRUB co-operate with the Dell bootloader are here. I have not tested them.

    • Alternatively, you can try the following steps when installing Ubuntu via the LiveCD (I have not tested them):
      1. Use the partitioning tool (gparted) to shrink the main Windows NTFS partition. Do not remove any partitions.
      2. In the free space that you just made, create your partitions for Ubuntu.
      3. Install GRUB to your /boot or / partition, not to the MBR.

      4. Set the partition that contains /boot to be active.
      5. Once installed, edit /boot/grub/menu.lst and disable the makeactive statement in the Windows section.

      6. Run sudo update-grub.

      -- SridharDhanapalan

  • For improved battery behaviour, enable laptop mode. In /etc/default/acpi-support, set ENABLE_LAPTOP_MODE=true. Then edit /etc/laptop-mode/laptop-mode.conf to suit your requirements, taking note of the warnings in the file. The defaults are a good starting point. You can find more information here and here. The official FAQ is here. -- SridharDhanapalan

  • Synaptics touchpad horizontal scrolling is disabled by default.
    • To enable it, edit /etc/X11/xorg.conf and look for the section that has an Identifier of "Synaptics Touchpad". To that section, add the following:

         Option         "SHMConfig" "on"
         Option         "LeftEdge" "1700"
         Option         "RightEdge" "5300"
         Option         "TopEdge" "1700"
         Option         "BottomEdge" "4200"
         Option         "FingerLow" "25"
         Option         "FingerHigh" "30"
         Option         "MaxTapTime" "180"
         Option         "MaxTapMove" "220"
         Option         "HorizScrollDelta"      "200"
         Option         "VertScrollDelta" "200"
         Option         "MinSpeed" "0.09"
         Option         "MaxSpeed" "0.18"
         Option         "AccelFactor" "0.015"
         Option         "EdgeMotionMinZ" "17"
         Option         "EdgeMotionMaxZ" "21"
         Option         "EdgeMotionMinSpeed" "30"
         Option         "EdgeMotionMaxSpeed" "35"
         Option         "LeftRightScrolling" "1"
         Option         "UpDownScrolling" "1"
         Option         "EmulateMidButtonTime"  "75"
    • You can now restart your X server using Ctrl+Alt+Backspace and horizontal scrolling should work.
    • Additionally, you could try installing the gsynaptics package and add gsynaptics-init --sm-disable to startup options in System, Preferences, Sessions.

    • If you want horizontal scrolling in Firefox instead of back/forward, do the following:
      1. Type about:config in the location bar.

      2. In the Filter field at the top of that page, type mousewheel.horizscroll to isolate all preferences of that type.

      3. Change the values of the *.action preferences to be 0.

      4. Change the values of the sysnumlines preferences to be true.

  • In Xfce (Xubuntu), the card reader does not appear in Thunar or on the desktop (Bug #75091). A workaround is to add the device node (/dev/mmcblk0p1) to /etc/fstab with the option user, then use the Mount Devices panel applet to graphically mount/unmount it. This is not a problem in GNOME (Ubuntu) or KDE (Kubuntu). -- SridharDhanapalan

  • Bluetooth: The GNOME OBEX client should be able to receive (but not send) files out of the box, provided that the bluez packages are installed and /etc/bluetooth/hcid.conf configured.

    • In KDE, some adjustment is required to permit two-way Bluetooth communication:
      1. In /etc/bluetooth/hcid.conf, use the option class 0x100000.

      2. You need to have passkey-agent --default /usr/bin/bluez-pin running. You can set it to run automatically when you log in.

      3. Make sure that KDE's Bluetooth services are set to run on start up.
      4. Even after this, you may find that KDE's standalone OBEX client (kbtobexclient) cannot find clients. You can still scan for devices via the command line (using hcitool scan) or through Konqueror's bluetooth:/ kioslave. The latter also allows you to transfer files.

  • IEEE1394 (Firewire): Firewire may not work after suspend/resume. A workaround is to reload the ohci1394 module. To have this taken care of automatically:

    1. create an executable file, /etc/acpi/suspend.d/59-generate-custom-modules-list.sh

    2. insert the following text:
         #!/bin/sh
         MODULES="$MODULES ohci1394"
  • Pressing Fn+Up and Fn+Down may either not function (Bug #74284) or may crash the X server (Bug #71433). The keys may work as expected after resuming from hibernation. According to this page, it's a problem with the acpi video module. Fixes (pick one):

    • Add the line alias video off to /etc/modprobe.d/local

    • Blacklist the video module.

    -- SridharDhanapalan, Snifer

  • Upon resuming from a suspend/hibernate action, the second CPU core is locked at its full speed. It will not throttle down. The first core behaves normally. This does not appear to be specific to Core 2 Duo CPUs. -- SridharDhanapalan

    • It affects Core Duo, also. Bug (and workaround): #64070. -- Snifer

  • Suspend ends with blank screen (no freeze, but no suspend and no resume). Bug (and workaround): #74330. -- Snifer

  • Audio may not function after resume. A solution is to add the line MODULES="snd_hda_intel" to /etc/default/acpi-support (Bug #74807). -- SridharDhanapalan

  • When running a graphical application from a terminal, you may see the message "X Error: BadDevice, invalid or uninitialized input device 166". A solution is outlined in Bug #42553. In /etc/X11/xorg.conf, comment out the lines

   InputDevice    "stylus" "SendCoreEvents"
   InputDevice    "cursor" "SendCoreEvents"
   InputDevice    "eraser" "SendCoreEvents"

Issues/Solutions with Edgy x86-64

  • Problem: Both CPU cores locked at maximum frequency after resume from suspend (1.83 GHz on T5600). CPU temperature climbs over 65C.
    • Workaround: Create script in /etc/acpi/resume.d/ with command: "invoke-rc.d powernowd restart" Details here. --TylerKinkade

  • Problem: Touchpad button AND tap-to-click frequently stop functioning. (Occurs almost every minute.) Bug No.70687

    • Solution: Add "notsc" to kernel options (x86-64 only, see above). --TylerKinkade

  • Problem: Super sensitive keyboard driver: characters repeat with a single tap. (This is not the same as the holding a key down to repeat feature: keyboard repeat delay is set to about 3 seconds.)
    • Solution: Add "notsc" to kernel options (x86-64 only, see above).

  • Problem: SLOW launch of simple applications: takes about 30-60 seconds to launch terminal, Firefox, etc. (The rectangular app launch animation usually advances at the slow speed of about 1 frame per 3 seconds.)
    • Solution: Add "notsc" to kernel options (x86-64 only, see above).

  • SLOW Ubuntu boot up: on the order of minutes. (WinXP boots in less than 30 seconds.)
    • Solution: Improved by adding "notsc" to kernel options (x86-64 only, see above).

  • Problem: No WiFi after resume from suspend.

  • Problem: Suspend/resume problems.
    • Solution: modify /etc/default/acpi-support as posted on forum here. --TylerKinkade

Issues with Breezy Badger

This is supposed to highlight dev release problems, but I am still working on getting Breezy working correctly. Also, I'm still getting my head around this wiki template. Without further ado, my problems are:

  • there seems to be an unresolved hardware issue with at least the Inspiron 9300 and 9400. Reproducible only on "affected" laptops and in windows: when system is +/- idle, toggle hardware radio switch (FN+F2) on then off again and leave at off. a ~high pitched whining noise starts, and goes away with radio switch back on, or while computer not idle; ie: if you open some windows, when computer is working, then goes away but comes back right after. any one have the same issue? some people have suggested a hardware vibration issue --purpleidea
  • Headphone jack does not mute internal speakers
  • Latest SMP kernel breaks keyboard.

(sorry for this but first time i edit a wiki ever !!!) I know how to fix that... the "/etc/hotplug/blacklist" file just add pcmcia and pcmcia_core and that will be fixed

  • SMP Kernel boots into X and then just before GDM loads it hangs with mouse perpetually doing "hourglass" spin thing -purpleidea
  • Intermittent heat-related issues -- not properly understood
  • gnome-terminal and xterms not closing properly -- become uninterruptible

Issues with Dapper Drake

  • Did not recognize my wireless (Intel Pro wireless 3945ABG) But the Wifi connectivity only works with the kernel provided on the livecd/installcd and does not work with updated kernels provided
  • Finds my Ethernet card but the DHCP client does not obtain an IP unless you down/up the interface.
  • The sound is very crackly, perhaps an interrupt issue.
  • The 1440x900 video resolution does not work. 1024x768 seems to work fine.
  • As of around Friday, weird hardware clock problems -- select() to /dev/rtc to wait for clock tick timed out. Seems to have been a common problem in the past, perhaps it has been unintentionally re-introduced? Commonly suggested --directisa workaround does not work.
  • /dev/agpart not available with 2.6.15 kernels, but works on 2.6.16.1. -JoelReed

  • Hibernate works, but after "wake up" screensaver automatically goes on even if in the middle of moving the mouse, typing, etc.
  • Hibernate works, but after "wake up" my screen is full with artifacts, so I have to logoff-logon, then everything is fine again. --morgengenuss
  • FN+F1 works to hibernate, but only for a first hibernate and when focus is on desktop. after wake up, to rehibernate you need to click logoff->hibernate.

  • wireless can be added (is not part of apt distro right now): http://ipw3945.sourceforge.net

  • SMP Kernel (stock or self-compiled -- latest versions) doesn't seem to work 100% CPU0 works fine, idles at 50% and goes up or down appropriately when needed. CPU1 either stays permanently at 50% or 100% (seems to boot up and randomly? be at either one or the other, and never throttles) anyone have the same problem? --purpleidea

Issues now fixed in Dapper Drake

  • Headphone jack does not mute internal speakers
  • and "jack sense" options aren't available in sound mixer
  • headphone issues are cleared up with alsa-driver-1.0.11rc4, see http://lkml.org/lkml/2006/3/17/279 -JoelReed

  • ALSA works, headphones broken again in latest source download from ALSA site. haven't checked CVS or above patch. is lkml patch supposed to be merged into regular alsa CVS? --purpleidea

  • I just updated my kernel to .20, and everything seems to just work now. Anyone else find this? --TennesseeLeeuwenburg2

  • headphones work for me in stock 686-smp kernel -21 --purpleidea
  • Hard disk spins down far too soon/often, no obvious control mechanism (i.e. in "power settings" or "disks" -- don't know where else to look)
  • FIX with "sudo hdparm -S12 /dev/sda" you can read about it on "http://gentoo-wiki.com/HOWTO_Use_hdparm_to_improve_IDE_device_performance" --DigitalLF

  • now i just found out in ubuntu you should edit /etc/hdparm.conf go to line 61 (spindown_time) and edit that to whatever you want --DigitalLF

  • This the spin-down on AC power, on Battery, on both. It is reproducible if you start from a clean reboot? -PaulSladen

  • AC Power, haven't checked with battery. Happens 100% of the time, reboots do not affect. --TennesseeLeeuwenburg2

  • The problem just ... went away one update. --TennesseeLeeuwenburg2

  • The built-in card reader does not work (Bug #63553). -- SridharDhanapalan

Notes

This is a first time edit on a WIKI for me (DigitalLF) but i will do all i can to help with anything on this laptop.

  • Excellent, many thanks for any testing you are able to do - hopefully you'll get a better experience out of it too! -PaulSladen

  • i have now found out how to get the wifi working and i get around 200kbs better speed in linux then i get in windows so it seems like it works great on my home-unencrypted network Big Grin :) -DigitalLF

  • I have compiled my own kernel and have been trying to install this. The install guide says to look for the firmware directory in 'hotplug.agent', a file which doesn't exist on my system. How did you get it to install? --TennesseeLeeuwenburg2

  • i dont have a clue about that but i dident even need to compile my own kernel its much easyer then that is there some way i can contact you msn/irc/skype? i'l walk you right through it its not that hard realy
  • I have added information about Edgy on a Inspiron 9400 but don't want to step on any toes. Made some edits in the interest of clarity and organization as noted above. Please contact me if I've offended anyone because that is not my intent. TylerKinkade

  • I've made a lot of additions and alterations. I can confirm that the problems mentioned by TylerKinkade are specific to x86-64 and are not present with x86-32. Also, the 'notsc' kernel option causes kernel panics with a x86-32 kernel. -- SridharDhanapalan

  • The "subwoofer" works in Feisty. -- Zapek
  • Been testing 8.10. Fried my Dell's Graphic card and possibly CD bay! -- D
