Current Issues

Issues with Hardware

* 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

Issues with Breezy Badger

* 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

* /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.

* 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

Issues now fixed in Dapper Drake

* Headphone jack does not mute internal speakers

* and "jack sense" options aren't available in sound mixer http://www.math.umd.edu/~olsson/jerome-install.html was recommended to me for fixing the line jack sense.

* 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

* 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

* 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

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 -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
