If this still happens with current git (ati-6.6-branch or master), please attach (as opposed to paste) full X config and log files. Requested information not provided in half a year. Feel free to reopen with the needed information. Created attachment 9972 [details]
XOrg Log File.
Whoops, sorry, I don't think I ever got the notification of the request and forgot all about this. The issue still stands although the laptop is being replaced this week.
I currently don't have an xorg.conf (XOrg is just running with auto-detected defaults which works just as well as all the previous configurations I've been through with an actual xorg.conf file).
XOrg.0.log attached.
Re-opening now that info is attached. Just shout if you need any other details (fyi I did also try the GIT version a month or two back with no noticeable improvements). The last line of the log file indicates you're using a GLX compositing manager such as compiz or beryl. Is that correct? If so, this is probably a duplicate of bug 8476. Ah, ignore that. I am RIGHT NOW, but wasn't before. The reason I'm using it now is it actually seems to speed things up slightly (I assume because it's using the 3D engine to do some of the tasks now instead). The issue is present with or without compositing. (In reply to comment #6) > The issue is present with or without compositing. Even before starting a GLX compositing manager for the first time? That hack used by your distribution effectively mostly disables 2D acceleration for the rest of the session when doing that (to make compositing usable with the deficiencies of XAA). Yes, even before that. This distro has been through Gentoo, Debian and Ubuntu and the poor 2D performance has been present throughout. Well, as there are no obvious problems in the log file, I'm not sure what to suggest except maybe to try xserver 1.3 with EXA and AccelDFS. For comparison, what kind of setup did you get adeuqate 2D performance with? My desktop is the only other thing I have to compare it to and the desktop is an Athlon64 X2 3800+ with an nVidia GeForce 7900GTO. I can confirm the exact same problem as mentioned in the first entry. I normally use a xinerama setup with two graphics card (ATI Radeon+Nvidia). The problem arises in Xinerama mode and also if I use a single head setup with ATI. It has not yet shown, when using a single mode setup with "nv". I have never used "compiz" or any other 3d hack. I'm not interested in 3d performance but 2d. This system runs dual boot of "Fedora 4" and "Fedora 7test4". FC4 work flawlessly. More information can be found at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227537 as I'm not sure where to post this bug. Probably here is the better place? This sounds exactly like the problem I'm experiencing on my system. Kubuntu 9.10 pre-release, 1.6.4-2ubuntu3 xserver, driver reports: (II) RADEON(0): Built from git commit 7968e1fb89f6b59d1654df48249bf4b81990c008 EXA is enabled and claims to be active, same for DRI. The video card reports itself as ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] This is a cheap 256MB X1550 AGP card. Not particularly reliable. The system is an Athlon64 2GHz, 3GB RAM, running a 64-bit kernel and userland. While glxgears chugs along with 11000 frames every 5 seconds, 2d rendering is absurdly slow, and the Xorg process eats up all the CPU. Most affected seems to be Thunderbird, which takes up to four seconds just to repaint after being covered. I'll attach the conf and log in a moment. Created attachment 30559 [details]

Xorg conf
I'm having the same problem (glxgears running at about 840 fps), but sometimes redrawing hangs when I switch desktops. Hardware is a RV630 (Radeon HD 2600), X is 1:6.13.1-2 on AMD64. If needed, I can supply xorg.conf and Xorg.log (In reply to comment #15) > I'm having the same problem [...] (In reply to comment #12) > This sounds exactly like the problem I'm experiencing on my system. [...] Peter and Sebastian, it's not clear that your problems are the same as the one reported here originally, as your setups are quite different and a lot of time passed in the meantime. Please file your own reports each with the full Xorg.0.log and dmesg output (assuming you're running with KMS enabled). As you mention high CPU usage, profiles obtained with sysprof or oprofile might be interesting as well. Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases. |
