slackware x86 -current + radeon: temporary screen corruption with kde4 applications

Hi all.

I'm running the latest slackware-current rc2 x86

I'm experiencing random screen corruptions when opening kde4 applications (akregator, konqueror, dolphin, the control panel, etc.). The screen becomes almost black and red, but the windows are visible (corrupted, but visible, like a "negative") and alive. X doesn't die or lock and when I close or minimize the application that triggered the corruption, the screen come back to its original "sanity". I can't figure out if it's a driver problem or a qt/kde4 problem. The gtk applications don't have this problem. I don't know how to reproduce the problem.

I'm using stock packages from -current, driver radeon (shipped with slackware). The DRI works. The corruption happens both using XAA and EXA, with and without composite, with kd4 and xfce. Nor /var/log/Xorg.log nor dmesg show anything useful.

Even if all the screen is corrupted, running a "import -screen" shows only the kde4 application in "negative".

I can't figure out if it's a X problem, a driver problem, a kde4 problem or a qt problem.

Based on your lspci output you can see the Identifier that you need to use. It is just before the brackets RV516.
03:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]

In this section of xorg.conf change the Identifier from "Card0" to "RV516". If you look at man radeon or man radeonhd you will see how I got this.

Thanks for your reply. Before you post, I completely removed the xorg.conf and I've not experienced screen corruption yet (after say 20 hours of uptime) . But it's too early too say. Over the next days I'll test your try too.

Anyway, I didn't see why naming the Identifier should fix the problem. In the man I didn't find anything and with the previous X a similar configuration has always worked without problem.Is this a kind of X black magic? Could you please point me to the documentation?

Thanks

My apologize, I looked at it a litle closer and the identifier shouldn't really have any effect on the video card's performance. But I would suggested trying a Driver "radeonhd" as it will support your video card.

Thanks for your reply. I suspect that Virtualbox 3.0.4 (and its kernel module) was involved, but I can be wrong (probably I am). For sure, Virtualbox prevented udev to create the proper device for a mp3 reader, and I suspect things are related. I had to clean the sistem to get my usb-storage working again (and so far, no more screen corruption). Strange, I know, and perhaps I'm wrong.

The radeonhd driver doesn't work well as the radeon here, but if I'll experience corruption again, I'll try to pull it from the git (both radeon and radeonhd).

I'm experiencing random screen corruptions when opening kde4 applications (akregator, konqueror, dolphin, the control panel, etc.). The screen becomes almost black and red, but the windows are visible (corrupted, but visible, like a "negative") and alive. X doesn't die or lock and when I close or minimize the application that triggered the corruption, the screen come back to its original "sanity". I can't figure out if it's a driver problem or a qt/kde4 problem. The gtk applications don't have this problem. I don't know how to reproduce the problem.

I'm using stock packages from -current, driver radeon (shipped with slackware). The DRI works. The corruption happens both using XAA and EXA, with and without composite, with kd4 and xfce. Nor /var/log/Xorg.log nor dmesg show anything useful.

I've experienced the same thing. It has happened to me 2 or 3 times. As you stated it happens on certain KDE4/Qt applications. It also happens on xfce and KDE4. GTK applications don't seem to be affected and not all Qt applications seem to be affected.

I run Slackware 13.0 x86 with an ATI x1400 and open source drivers. The last time I ran into this problem Konqueror had just crashed and that is when the Black and Red screen corruption happened. When Konqueror crashed I also had Konsole and Firefox open and they were unaffected.

I don't have any solutions but just to say this has happened to me as well.

Sorry to bring this thread up again, but I'm having the same issues with Slackware 13, on my Dell laptop. Video card is an ATI Radeon Xpress 200, using the radeon driver. This has not happened to me in XFCE as of now, but it sure happens in KDE randomly (but permanently for each and every Qt app opened after the first one gets corrupted)

Sadly I have nothing to add to the thread, but of course I'm willing to try anything suggested :-)

Regards.

I've seen something similar with one or two KDE/QT apps. Someone suggested setting XLIB_SKIP_ARGB_VISUALS to 1 before launching those applications, and when I did that the problem stopped.

If you have a specific application that consistently causes this problem, you could try setting that variable from a terminal and then launching the application from that terminal to see if the problem happens then.

I saw somebody mention that on ##slackware but it didn't work for me after the problem showed up again.

If I can kill this problem then I have no other gripes with KDE4.

I can confirm that the negative screen behavior is due to VirtualBox. I noticed the same problem only when running VirtualBox. I also found that moving or resizing VirtualBox windows causes the windows or the display to become a sort of transparent rectangle.

The strange thing is if I set VirtualBox to use "seamless" mode I only have a problem when first starting a virtual machine or displaying some KDE applications such as System Monitor. If I click anywhere on the KDE desktop then the screen displays correctly and "seamless" mode works fine.

The work around is to disable the desktop effects in KDE. Then VirtualBox doesn't cause problems. VirtualBox also works with XFCE even with the window fading effect.

I have a couple of virtual machines, and lately I've been playing a lot with them (for MSN videoconference and the OVI Suite, mainly), so VirtualBox has surely been there all the time.
I'll try today to run KDE without starting VirtualBox and see what happens. Do you think removing the module from the kernel is also required?

Yeah, I just started up VirtualBox twice and both times caused Konsole to exhibit the same behavior. Only workaround for me was to restart X.

Not sure what you mean by "seamless" mode.

Desktop effects are turned off on my system and I still see this problem. When I turned desktop effects on I was unable to view video in vlc and smplayer. So, that doesn't seem to be a solution for me.

I like VirtualBox but it has always had quirky screen display issues, especially with Linux. VirtualBox worked better with Linux before Innotek was bought by Sun, however Windows was not as solid. Now Windows support is much better but Linux seems to be a problem. I would be happier if Sun made less frequent releases that had less bugs, or at least did a well tested "stable" release once in a while.

Lest I sound like a "whiner" there have been a lot of great features added to VirtualBox and I still prefer it even with a few bugs to Microsoft Virtual PC.
