Notes
(1) |
Works with v4l2 but not with v4l. But most applications support v4l2 nowadays (ekiga, cheese, skype), so this is almost a non-issue. |
(2) |
Technically this works perfectly with the xrandr tool. The GUI shipped with hardy has many problems however. I could not get it to expand the desktop for instance. |
(3) |
Strangely this key produces the following keysyms in xev: Alt_L (press), KP_Insert, KP_End, KP_Down, KP_Up, Alt_L (release) |
(4) |
There is an issue which seriously affects video performance with 4GB of RAM (see 210780) |
(5) |
Compiz will only work with combined resolutions up to 2048x2048 pixels. This is a driver bug that apparently is fixed in Xorg trunk! |
(6) |
X will be limited to the maximum supported resolution of the devices connected on startup. If you want to plug in a higher-resolution display after startup or if you want to extend your desktop (aka. multi-head), put in an appropriate Virtual width height line into your /etc/X11/xorg.conf (More detailed explanation). |
(7) |
SD cards work, MMC cards can be made to work with a kernel patch, XD and MemoryStick are not supported due to the manufacturer not providing specs AFAICT |
(8) |
The display backlight is switched off automatically by the hardware but HAL does not notice the lid close event. |
(9) |
After resuming from suspend or hibernate, sound is no longer working (see 200210). |
(10) |
The screen blanks but the backlight actually stays on! |
(11) |
You can let the hardware do it via a BIOS setting but I disabled that. |
Workarounds
Workaround for "Fails to boot"
To get the LiveCD to boot, pass acpi=off as kernel parameter
- Then install Ubuntu normally
When booting the installed system you must again pass acpi=off
Then blacklist the video kernel module:
echo "blacklist video" | sudo tee /etc/modprobe.d/blacklist-q45
Reboot without passing acpi=off
Workaround for "MTRRs set up incorrectly with 4GB RAM (slow video)"
A workaround with a useful script is described here: 210780
Please note that you may have to modify it and that not doing that or doing it wrong may well freeze your system and/or render it unbootable! Do this only if you know what you're doing
Workaround for "Sound does not work after resuming from suspend/hibernate"
Add the option model=hippo to the snd-hda-intel driver:
echo "options snd-hda-intel model=hippo" | sudo tee /etc/modprobe.d/sound-q45
- Reboot
Workaround for "Card reader cannot read MMC cards"
The kernel patch that has to be applied can be found here: RL5c476 MMC support.
- You have to recompile the ricoh-mmc module with this patch applied and replace the driver in Ubuntu with the new one.
sudo modprobe -r ricoh-mmc
sudo apt-get install build-essential linux-headers-`uname -r` wget
mkdir ~/ricoh-mmc-fix
cd ~/ricoh-mmc-fix
wget -O ricoh_mmc.c 'http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=drivers/mmc/host/ricoh_mmc.c;h=a16d7609e4eede4fa88f4ecc6b3ac9dce699038a'
echo -ne "obj-m += ricoh_mmc.o\nall:\n\tmake -C /lib/modules/\$(shell uname -r)/build M=\$(PWD) modules\n" > Makefile
make
sudo mv /lib/modules/`uname -r`/kernel/drivers/mmc/host/ricoh_mmc.ko /lib/modules/`uname -r`/kernel/drivers/mmc/host/ricoh_mmc.ko.hardy
sudo cp ricoh_mmc.ko /lib/modules/`uname -r`/kernel/drivers/mmc/host/ricoh_mmc.ko
sudo depmod -a
sudo modprobe ricoh-mmc
