X server restarts on starting qt apps
Last modified: 2008-12-29 15:54:21 EST
Description of problem:
X.Org X server 1.5.3 crashing
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install texmaker from the package manager.
2. Open it from the Applications/Office menu
Application doesn't start and X server restarts
Texmaker to start normally.
Running kernel 126.96.36.199-117.fc10.i686 on Fedora 10 updated to rawhide.
works fine here for me.
imo, X crash -> X server/driver bug.
Fwiw, what video hardware/driver are you using?
Also works fine for me. You can also check out the new 1.8 release in updates-testing  to see if it make a difference for you (although it's weird that texmaker is causing xserver crash)
Peace be upon you all,
For the first question I use openchrome-0.903 driver.
I noticed the following when I tried to install and run KDE 4: NO QT-4 or KDE 4 based application runs and X crashes. What made me think about that it might be a QT based problem is that both texmaker and Lyx share the same problem, this was ensured by the fact that KDE 4 doesn't even initialize on my machine. Please help me with this.
OK, evidence points to X issue, reassigning.
In the meantime, you could try booting (at grub menu) with:
to avoid using openchrome, to see if that helps.
Peace be upon you all.
Before reading your last comment, I made the following change to xorg.conf.
# Driver "openchrome"
I restarted X. Everything went fine concerning QT based issues. I wonder what is wrong with QT-based applications and the openchrome driver. If there is a problem how to solve it since working with the vesa driver makes things very much less speedy. I tried to add some options like the MigrationHeuristic and greedy options but those didn't make X even start. The openchrome man page doesn't show what are the Options in the openchrome driver used in any particular situation. I don't have to give every option a trial to make things work. Isn't there any detailed document that describes each option and its uses?
Thanks in advances.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
