GNOME Bugzilla – Bug 112486
Logout effect hideously slow
Last modified: 2004-12-22 21:47:04 UTC
So I'm running on a Celeron 414 MHz machine with a Permedia2 8MB video card with RedHat 8.0 X setup and the logout effect is way too slow. First the dialog shows up, and then I can see each frame in the animation, one by one. I'll try to see if it is some problem with my video card setup, but I just let RedHat configure it so this could happen to many other setups.
I see the same thing using an athlon 1.2G with a 32MB tnt2 video card
Can you tell us approximately how many seconds/minutes it takes? "too slow" is not very informative.
No I don't have timings, but I stated what I see. I can see each frame individually change, instead of a smooth effect. It's really ass ugly. Anyways, the old logout effect looked just fine, and RH has a nice fade out effect for the screensaver that works fine on my setup.
I see about 6 to seven frames in ~2 seconds. Also my mouse moves at 3 fps which makes it really hard to select the "halt" option. I always have to wait until the effect has finished. I consider this a bug :) (My PC runs with a Nvidia Riva TNT with the Nvidia drivers).
Perusing through the new Fedora list I notice the following thread which indicates that lots of people are seeing this. http://www.redhat.com/archives/fedora-test-list/2003-September/msg01243.html
I tried to troubleshoot this in #gnome-help and it was suggested that it was because my bit depth was too low (16 bit). I changed it to 24 bit and it had no effect. My video card isn't very fast, it's an Intel 855GM (Centrino Laptop).
This is a particulary odious "feature" for remote sessions, regardless of hardware issues. A GConf entry for turning this off would be greately appreciated and presumably quite simple to implement for those skilled in the arcane arts of GConf.
Fresh install of everything over here, topped off with GNOME 2.5.3 from source on my laptop (ATI rage128-class, 1600x1200), and the log- out is probably the slowest thing on this machine. It takes a around three seconds to do all of the drawing needed, which is bad compared to about 6 seconds to boot X and GNOME. Note that DRI works fine and OpenGL screensavers have no problem on this machine. The main problem isn't even the effect, as much as the noticeable slowdown and drawing problems.... sometimes only certain areas of the screen get painted before it skips to the next shade of gray, and the slowdown keeps me from doing a quick click on the confirmation dialog. Only reason I haven't noticed this before was because my old install (Gentoo, GNOME 2.5 ebuilds) patched-out the logout dialog and used GDM for shutdowns.
