Description

Please try to determine what update caused the problem for you. If we know which package is the point of regression, it'll be easier to diagnose. Also, please disable VNC to take it out of the equation for now. Does the problem occur without vnc loaded? Took VNC out of the equation, the problem remains. I'm not sure it actually
changed the behavior, or I was just attaching to the X server too late in
previous attempts. This time I switched to VT1, logged in as root, started
strace on the running X (this time, on the SSH agent passphrase prompt, right
after logging in) with syscall output to a file. When I switched back to VT7, X
repainted the entire screen except for the SSH agent window, and then it
stopped. This is a snippet from the strace output, that appears to be relevant:

[...] (repeats forever)
I suppose I can get to earlier versions of X packages out of the internal Red
Hat build system, but would you hazard any as to which package this might be
related with? This would surely help narrowing down the big and painful search
I have ahead of me :-) Thanks,
This got fixed in yesterday's rawhide. Yay! |
