Hello,

I am fairly new to Linux and decided to play with it for a while on both of my computers. KDE's the only desktop environment that doesn't look awful to me, so its what I went with

Everything works perfectly pretty much out of the box on my home computer, but my work computer here has issues with the application launcher. No matter which variant of it I use (Besides classic) the graphical effects will "stop." If I hover over one of the Favorites/Applications/Computer/etc tabs it won't switch to them anymore, unless I approach it from underneath with the mouse touching the taskbar first. If I hover over menu entries it doesn't show the little blue rectangle that surrounds it with the subtext for the menu entry. Keyboard controls still work as expected.

Whenever this starts Chromium starts to freeze up which makes the computer unusable. If I log off the session and start a new one everything works fine again for a while.

I have no idea how to begin debugging this problem and any input would be appreciated. I hope this was clear enough... Also I'm on Intel graphics with a GM45 although I'm not sure that will make a difference.

Thanks

Can you try checking the memory usage of your system, to see if the computer could possibly be swapping?

Hi,

It turns out the problem wasn't related to KDE at all, it was a glitch in the evdev package on Arch. I downgraded and everything is working perfectly. I found it was the problem totally by chance but I'm glad its fixed now

If anybody ever runs into a similar issue, the problem is evdev is not playing nice with touchscreen interfaces for the moment. It forces your applications to lose focus which gives the appearance of freezing and unresponsive widgets. All you need to do is downgrade the evdev to fix it.

Thanks for your help!

Interesting - haven't seen that before.
Thanks for posting the solution - marked as solved.
