I also get this problem on Kubuntu 10.10 w/ KDE 4.5.1, Lenovo ThinkPad X301 2776-C1G 8GB
Mouse locks up on login. Caps lock light no longer works, although I believe the system is still alive at some level, as when I press the power button the hard drive light comes back on for a while, at least before I give up waiting and hold it down again for 8 seconds. Workaround was to remove Desktop Effects by booting into single user mode, editing ~/.kde/share/config/kwinrc and commenting out the following lines: [Plugins] kwin4_effect_blurEnabled=true kwin4_effect_coverswitchEnabled=true kwin4_effect_desktopgridEnabled=true kwin4_effect_dialogparentEnabled=true kwin4_effect_explosionEnabled=true kwin4_effect_fadeEnabled=true kwin4_effect_loginEnabled=true kwin4_effect_logoutEnabled=true kwin4_effect_magiclampEnabled=true kwin4_effect_maketransparentEnabled=true kwin4_effect_minimizeanimationEnabled=true kwin4_effect_presentwindowsEnabled=true kwin4_effect_scaleinEnabled=true kwin4_effect_shadowEnabled=true kwin4_effect_slideEnabled=true kwin4_effect_taskbarthumbnailEnabled=true kwin4_effect_thumbnailasideEnabled=true kwin4_effect_wobblywindowsEnabled=true System works normally after that, so perhaps one of the above plugins are the cause. -- [GM45] GPU Hang when enabling KDE desktop effects https://bugs.launchpad.net/bugs/644740 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
