KDE desktop repeatedly hangs

mfoley · 09-04-2016, 11:22 AM

I just installed a new Slackware64 14.2 on 2 laptops a few days ago, and am using the "default" KDE desktop. On both computers, after some period of time, the keyboard totally hangs -- I can type nothing. The mouse still moves, but clicking on anything has no effect. I have to power down the computer or, if I am ssh'd in from some other computer I can `shutdown -r now`.

This kind of makes these systems unusable. Any idea what's up and how I can fix it?

There should be an x-session error log in your home directory.
~/.xsession-error

Unfortunately, there are no timestamps in this file, so I have some trouble correlating. Here's what I find:

Code:

Does this tell you anything? I've made a note of the last line number, so I'll check events after that the next time it happens.

Modify your visudo file so you don't have to run this application as root.

mfoley,
Did you happen to verify your install medium by checking the md5sum?
The same symptoms on 2 different (they are different, yes?) machines suggests a problem with the software. Could be that the install medium was corrupt somehow.

I used the same backup tarfile to create the 2nd machine installation.

However ... I booted the 2nd machine and noticed that USB devices were not being found during the boot process -- boot delaying trying to communicate with USB. When the machine came up, no mouse/keyboard. I rebooted and same thing. So, I tried booting the Huge kernel instead of the generic. It's been 2 days with no problem and 8+ hours of constant use today on 2 screen will lots of windows open including Firefox, a few Konsole's and a WIN7 Virtual Machine. I'll give this another day or two, then I'll try rerunning mkinitrd and switch back to the generic kernel. I'll post results.

dijetlo: I don't believe I'm running the application as root. What makes you think I'm doing so?

Interestingly, I do have additional "X Error: BadWindow (invalid Window parameter) 3" errors in my ~/.xsession-errors file, but no mouse/keyboard hangs so far.

I think he was replying to the wrong thread about something. The reply didn't make sense to me, either.
