Current Issues

The rotate and mobility buttons do not work. These buttons are located on the lower right part of the screen, just right of Altec Lansing.

This laptop suffers from the laptop harddrive Load_Cycle_Count issue. The "ugly fix" suggested in that thread needs to be updated, here you can read my fix (to the ugly fix).

In case the RAM is upgraded to more than 2GB a resume from suspend to RAM can ruin your filesystem, see note 10 below.

Hardware details

Notes

1) 3D works with both nvidia-glx or nvidia-glx-new driver packages, but the latter has some problems: a flickering text console and a flickering screen after a DPMS blank of the monitor, e.g. when the lid is closed and reopened. With nvidia-glx drivers there is the need to add a line with Option "AddARGBGLXVisuals" "True" in the Device section in /etc/X11/xorg.conf to have decorations with Compiz. It has been reported that the latest nvidia driver (173.14.05) works without these problems on Hardy.

2) In order to get a working sleep and hibernate I configured the system as follows:

2a) Add a line with echo 2115985408 > /sys/power/image_size in /etc/rc.local;

2b) Add a line with Option "NvAGP" "1" in the Device section in /etc/X11/xorg.conf;

2c) Deactivate Sync To VBlank from CompizConfig Settings Manager, General Options, Display Settings;

2d) Add the vga=0 option in grub;

2e) unload ehci_hcd module on suspend, i.e. put a file in /etc/pm/config.d (e.g. /etc/pm/config.d/modules) with SUSPEND_MODULES="ehci_hcd" in it.

After resuming from sleep the webcam doesn't work (adding uvcvideo to the list of suspended modules fix this problem, credits for this fix go to Ubuntu forums poster dudafmendes) and the touchscreen sometimes loses calibration (switching to text console and back fixes this problem).

3) The wireless chip is a Broadcom BCM4328 which is not yet supported by b43, so ndiswrapper must be used. EDIT: I have recently (Nov. 22 2008) learned that the wireless chip also works with the wl driver which is included in the linux-restricted-modules-<kernel version> package. The wl module requires that the ieee80211_crypt_tkip module is already loaded to work (but wl doesn't depend on ieee80211_crypt_tkip), and obviously that other modules, like ndiswrapper that control (or attempt to control) the wireless chip are not loaded. The module is not loaded automatically, so to have it working I did the following:

3a) put a file in /etc/modprobe.d (e.g. /etc/modprobe.d/wl) with the following content (in one line)

install wl /sbin/modprobe -r ndiswrapper b43 bcm43xx b43legacy; /sbin/modprobe ieee80211_crypt_tkip; /sbin/modprobe --ignore-install wl

3b) add a line with wl to /etc/modules, e.g. my /etc/modules now reads as

# /etc/modules: kernel modules to load at boot time.

#

# This file contains the names of kernel modules that should be loaded

# at boot time, one per line. Lines beginning with "#" are ignored.

fuse

lp

rtc

wl

Actually, the unloading of ndiswrapper, b43, bcm43xx and b43legacy modules is not needed, because these are not automatically loaded, but just to be safe I have added the unloading command. I have read that the ssb module may conflict with wl, but on my system the wireless works with both ssb and wl loaded.

4) The modem is a Motorola model SM56 Si3054. See this page to make it working. Following the instructions there I was able to activate the modem and made a telephone call, but I haven't tested a dialup connection.

5) See this thread about the fprint project.

6) There are two alternative drivers for the touchscreen. The free evtouch driver and the binary driver by eGalax. I'm using the evtouch driver repackaged with the patch I suggested in the bug report. Here it is possible to download the package for x86_64.

7) See the LCD Screen Buttons section in the LaptopTestingTeam/HPPaviliontx1220ca page to identify the buttons. The working ones have already an assigned keycode.

8) With kernel version prior to the Hardy one, such as those found on Gutsy or Feisty, there was the need to add some kernel option to boot (e.g. noapic, nolapic, etc.). These options are no longer needed and can actually hinder a proper functioning of the system.

9) To upgrade the bios I have successfully used a Vista live CD as explained here.

10) Bug 203537 seems to arise on the tx1000 series if you have more than 2GB RAM. It can be fixed adding iommu=soft to the kernel boot options, see the bug report discussion and this post. Thanks to Ubuntu forums poster pmaconi for pointing out this problem, confirmed by Ubuntu forums poster isachan.
