Current Issues

Quite substancial regressions from Breezy,

  • Hotkeys only work with upgraded pcc_acpi driver [1]
  • Does not wake from suspend
  • Does not wake from Hibernate
  • Sdcard driver works unreliably (sdhci)

The following are serious regressions from breezy and render the laptop a lot less useful. [https://launchpad.net/distros/ubuntu/+bug/33855 33855],[https://launchpad.net/distros/ubuntu/+source/acpi-support/+bug/31525 31525], [https://launchpad.net/distros/ubuntu/+source/acpi-support/+bug/35170 35170], [https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/35973 35973]

Notes

  • [1] Driver Crash:

The current (as of flight 5) pcc_acpi driver crashes when the function keys are pressed. When this driver is used, the first key press works, but then causes a kernel oops. Subsequent presses fail. The solution is to upgrade to the new version of the driver (http://www.netlab.is.tsukuba.ac.jp/~yokota/archive/pcc-acpi-0.8.2-hy20060126.tar.gz). This fix has already been committed by Ben Collins according to bug #33855, so should show up in future updates to the kernel.

  • [2] Sleep troubles:

The laptop successfully sleeps if I use GPM to click the suspend option. It sometimes sleeps if I shut the lid. Somtimes it does nothing (misses the event I guess).

  • It would appear from other reports that the pcc_acpi kernel module maybe busted -PaulSladen

  • I agree. I am tracking this in bug 35170. I thought that the solution was in 33855 but this was rejected -JohnStowers

  • [3] Brightness and Volume Keys:

Once the new pcc_acpi driver is installed, the brightness keys are correctly handled by /etc/acpi/events/panasonic-* scripts. The /etc/acpi/panabright.sh script needs some minor changes in my opinion. The volume/mute keys do not have handler scripts to call the appropriate acpi_fakekey number. See proposed patch for acpi-support in bug [https://launchpad.net/distros/ubuntu/+bug/16424/ 16424]. After patching these scripts, the mute, volume down, and volume up keys generate X11 key numbers 160, 174, and 176. These key numbers can then be mapped to virtual keys or handled directly by the window manager.

  • [4] SD Card Slot:

Works (slowly)

  • Currently the driver only works in MMC mode. How slow is "slow"? -PaulSladen

  • About 20-30 senconds to transfer a 2mb image. About 3-5 mins to thumbnail 100Mb of pics off the card -JohnStowers

  • [5] External Monitor:

Using the i810switch utility works perfectly. I am unaware of any other easy means to enable the external monitor on this laptop.
