This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping 3d (compiz) was working fine until the latest update for me xorg-x11-drv-radeonhd-1.2.3-1.6.20081128git.fc10.i386 glxinfo shows that it is using the software rasterizer .. is the mesa dri opengl thingy at fault here? As stated .. it worked fine with the last version, but a recent update broke it. Radeon X1650 card I recently heard something like that the white screen (intentionally?) comes when compiz can't get hardware acceleration. So, yes, the problem seems to be that hardware acceleration has been lost somehow. I could imagine that it could be related to the introcuction of kernel mode setting ... Could you try booting with "nomodeset" on the kernel command line to check this out? Then I could unify three open bugs into one "DRI or KMS, choose one" bug. nomodeset makes no difference, so i dont think its the modesetting in the kernel I have just some more experiments. I cant get either the radeon or radeonhd drivers for xorg to do 3D .. and glxinfo reports using the software rasteriser. This is is with kernel 2.6.27.7-134.fc10.i686 For the sake of completeness, I went back to the previous kernel. 2.6.27.5-117.fc10.i686, and lo and behold 3D works, and glxinfo reports OpenGL vendor string: DRI R300 Project OpenGL renderer string: Mesa DRI R300 20060815 AGP 8x x86/MMX+/3DNow!+/SSE TCL OpenGL version string: 1.3 Mesa 7.3-devel looks like a kernel issue after all The Radeon HD 3200 on my HP tx2617ca also is using the software rasteriser, and radeon and radeonhd end up without 3D acceleration, and compiz thus leads to a whitescreen. I had this problem with my X1300, turns out that DRI is disabled by default, see the line in the attached log that says: (II) RADEONHD(0): Direct rendering turned off by default. Use Option "DRI" to enable. Adding: Option "DRI" "on" Got me those fabulous wobbly windows. Also worth noting, however, that I disabled modesetting with nomodeset. It may not be required, but I've seen plenty of people say it is, and I disabled it because it was causing the keyboard/display to hang with the other (radeon) driver if X restarts or I switch VTs. I saved the plymouth boot with vga=792.

I have noticed it on installing Fedora with users already created that had desktop effects enabled before. All works again when I install Nvidia drivers, that are not in the main repository. I think there should be a way of disable automatically (for that session at least) desktop effects if compiz can't get hardware acceleration instead that pretty white screen. Maybe bugs #461459 and #444977 are related. This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Long time no see. Closing. |
Created attachment 321722 [details] X log from session with problems - but nothing is logged because of that Description of problem: radeonhd generally works fine (at least with a nomodeset kernel) and it seems snappier than the ati/radeon driver. BUT when I log in as a user with Desktop Effects enabled then I see desktop icons for halv a second on a white background, and then everything gets white. Switching to other X's with ctrl-alt-Fn and back again works fine. Desktop Effects works better (but with other problems) with ati/radeon driver, so I assume that the problem in this combination is related to radeonhd. FWIW glxgears works fine, I assume that shows that some of the "advanced" X stuff works. I have a plain xorg.conf in order to use radeonhd instead of auto-selecting ati/radeon driver. AFAICS there is nothing interesting in the X log. Hardly any difference between the one with compiz and the one without. They do however all have a strange "ascii" 80 in (II) RADEONHD(0): On Crtc 0 Setting 59.9 Hz Mode: Modeline "<80>" 119.00 1680 1728 1760 1840 1050 1053 1059 1080 +hsync -vsync lspci says 01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series] 01:00.1 Display controller: ATI Technologies Inc RV516 [Radeon X1300 Pro] (Secondary) Let me know if I can provide anything useful for debugging.
