Notes

Anchor(footnote-webcam)(1)

Works with v4l2 but not with v4l. But most applications support v4l2 nowadays (ekiga, cheese, skype), so this is almost a non-issue.

Anchor(footnote-xrandr)(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.

Anchor(footnote-euro)(3)

Strangely this key produces the following keysyms in xev: Alt_L (press), KP_Insert, KP_End, KP_Down, KP_Up, Alt_L (release)

Anchor(footnote-mtrr)(4)

There is an issue which seriously affects video performance with 4GB of RAM (see [https://bugs.launchpad.net/bugs/210780 210780])

Anchor(footnote-compiz2048)(5)

Compiz will only work with combined resolutions up to 2048x2048 pixels (this is a hardware limitation)

Anchor(footnote-virtual)(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 ([http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#the_Virtual_screen More detailed explanation]).

Anchor(footnote-cardreader)(7)

Tested only with an SD memory card

Workarounds

Anchor(workarounds)

Workaround for "Fails to boot"

Anchor(workaround-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)"

Anchor(workaround-mtrr)

  • A workaround with a useful script is described here: [https://bugs.launchpad.net/bugs/210780 210780]

  • Please note that you may have to modify it and that not doing that or doing it wrong may well freeze your system!
