Bug Description

Binary package hint: xserver-xorg

I have both Edgy & Dapper installed on my Toshiba Portege 4830CT notebook. When I boot Edgy, window repaints (e.g. when moving a window) are painfully slow. The video card is an S3 Inc. 86C270-294 Savage/IX-MV.

I am using Enlightenment 16 as WM. CPU usage spikes to 100% when moving a window around the screen, and a repaint of a medium-sized window takes over 1 second, whereas on Dapper itś smooth and fast. I highly doubt itś the fault of the WM, but will test with fluxbox shortly and report the results here.

Fluxbox, too, is affected. The problem is so bad that when Gaim repaints its chat window when somebody sends a message, it causes the sound to get choppy from the CPU spike.

I'm not comparing this to Dapper, but I'm seeing 70-80% cpu usage for xorg. If I open a program like Thunderbird, it drops to 60% until the program loads and then goes back up to 80%. At one point there was 45% xorg and 45% nautilus. I killed nautilus, it reloaded, and then xorg went back up to 80%. I'm viewing this in top.

Shortly after I reported the 80% cpu usage of Xorg, I ran gnome-sudoku. After play, the program began to send a bug report. After that was completed, I noticed that Xorg was using under 10% cpu as expected. I have no idea what caused the change, but I had done nothing but play that game for 10 minutes, quit, let the bug info collection run, and then observe top.

For some reason, my Edgy X.org install did not auto-detect the S3 Savage card on the laptop, so I was running with the VESA driver. Have changed to the śavage' driver and things now work great. Feel a bit foolish now :-) Please close.
