Ubuntu 10.04 lucid

set window operating buttons back to the right side


gconftool-2 -s /apps/metacity/general/button_layout --type=string "menu:minimize,maximize,close"

upgrade problems on Samsung Q25


but seems to be rather this issue: http://www.ubuntu.com/getubuntu/releasenotes/1004#Intel%208xx%20X%20freezes/crashes


boot with the -vesa video driver

other choice: use a newer Intel Video driver 2.11git:

upgrade xserver-xorg-video-intel to 2.11git


sudo add-apt-repository ppa:glasen/libdrm && sudo apt-get update && sudo apt-get upgrade
sudo add-apt-repository ppa:glasen/intel-driver && sudo apt-get update && sudo apt-get upgrade

to downgrade (if you want to try your luck with the official lucid driver again): Have a look at http://packages.ubuntu.com/lucid/xserver-xorg-video-intel for the version number and check the changelog: aptitude changelog xserver-xorg-video-intel. (Then remove the PPAs - maybe this is not needed or good...). Now downgrade:

sudo aptitude install xserver-xorg-video-intel:2:2.9.1-3ubuntu5

not tried yet...

use mainline kernel

other possibility: see: http://forum.ubuntuusers.de/post/2472917/

UXA rendering and external monitor at 75 Hz

now the easiest and best situation: https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes#Workaround%20F :%20Use%20UXA%20Rendering reenable KMS, set UXA Rendering in xorg.conf, reinstall drivers from ubuntu's repos instead of glasen's (maybe not needed or even not ideal) and set the freq of the external monitor to 75 Hz (to prevent flickering): https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/589140/comments/15

use the GTT Incoherency Patch


working great (2010-10-04)
