Version: (using KDE 4.2.0) OS: Linux Installed from: Ubuntu Packages When issuing either of xrandr -o left or xrandr --output LVDS --rotate left KDE will momentarily repaint in a rotated state (but with panel in the middle, as in bug 162856), then momentarily repaint with corruption (the bottom 3/4 of the screen consists of purple lines), and then totally crash dropping me back to gdm. I am happy to provide any info you need to debug this. This is a Toshiba tablet laptop, with intel integrated graphics. Ubuntu intrepid and KDE 4.2.0 from the http://ppa.launchpad.net/kubuntu-experimental/ubuntu repositories.
After further testing, this appears to be a kwin bug. When I run gnome, and replace metacity with kwin, the desktop crashes and boots me to gdm. When I run kde, and replace kwin with metacity, the desktop rotates perfectly in all aspects. If someone could reassign the product, I would be grateful.
Just noting that rotating with compiz works fine, so the problem is not just that kwin is a compositing window manager.
I would like to confirm this bug in 4.3. It has actually been a problem since 3.5, if I remember correctly, but just decided to come checking here. Basically rotating causes about a third of the right side of the screen to show up on the left third of the screen (in rotated direction) with the rest being covered in noise. An X crash follows quickly thereafter. This is on a Thinkpad X60 tablet with onboard Intel graphics card. The resolution is trying to go from 1400x1050 to 1050x1400.
Hello, Antonio; I have discovered that disabling desktop effects (in system settings) allows me to rotate perfectly. Is this the case for you as well?
Ah, yes. Turning off effects still has the screen flash once with plasma not having adjusted, but it finalizes the rotation.
Reassigning as per suggestion in comment #1
What exactly is crashing? X Server, plasma or kwin? In case of the first any useful information from /var/log/Xorg.0.log is appreciated. In case of plasma or kwin a crash report would help.
Is this still an issue? I just tried and it works fine.
Sorry for not getting back to you back in September. I actually no longer have a computer running latest KDE in my possession, so I can't check to make sure this no longer causes issues. Hope someone else with this problem will step up and indicate whether or not its still a problem.
I haven't experienced this issue for a very long time. Looks like it's been fixed! :)
