I'm using the KDE5 desktop environment and I've attached the appropriate log files. The dmesg output is the same before and after the monitor power cycle, the other files have the suffix _good and _bad. Now there are lines with "get vblank counter failed: Invalid argument" in the Xorg.0.log file, which I didn't see previously. This all looks like a random problem, maybe the use of an unititialized variable or an out of bounds array access.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
