Adding nomodeset fixes this on my Dell Inspiron 500m with a 82852/855GM and a 1400x1050 display, running kernel 2.6.31-15-generic and Xorg from the xorg-edgers ppa (xorg 7.4+3ubuntu10 and intel driver 2:2.9.1~git- 0ubuntu0tormod).
With KSM, watching a DVD with Totem, the framerate goes down to almost 1 fps. VLC is almost ok, 10% of frames dropped with 100% CPU load. Without KSM, VLC is perfect but Totem goes nuts: viewing a DVD works sometimes when using a small window, but never full-screen. It looks like the UI is on top of the video. Also, I think disabling KSM caused another problem: when waking up from suspend-to-RAM for the first time, the display resolution came up lower than normal, and playing a DVD with VLC on XVideo caused a hard lock-up - not even Alt-SysRq-K,S,U,B could boot the machine. I tried suspending again manually after rebooting, and now it worked correctly. The lock-up occurred after the laptop had supended automatically due to being idle (I've set a 30 minute timeout for suspend). I'll keep an eye on the issue and see if there's a specific bug report for it. -- [i855] No Xv support for 82852/855GM (KMS bug) https://bugs.launchpad.net/bugs/395932 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. _______________________________________________ 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
