Title: Graphics glitches after upgrade
Post by: Crust on 2015/10/13, 18:53:27

After a recent dist-upgrade, my graphics is glitchy - especially when scrolling, things are not smooth and sometimes there is corruption of graphics.

1. I use kdenext.
2. from inxi -v3:

Code Select


Graphics:  Card: Intel 3rd Gen Core processor Graphics Controller bus-ID: 00:02.0
           Display Server: X.Org 1.17.2 driver: intel Resolution: 1920x1080@59.94hz
           GLX Renderer: Mesa DRI Intel Ivybridge Mobile GLX Version: 3.0 Mesa 10.6.8 Direct Rendering: Yes

3. I am so confused on how to read logs as I have, unfortunately, not been able to keep up with systemd and its associated changes.

Apparently, the system is not updating Xorg.0.log anymore.

Running journalctl returns nothing (I don't know why)

Code Select


$ journalctl
No journal files were found.
-- No entries --

My guess is that this is due to the acceleration used and potentially the composition used in kde. In the past, I was able to check acceleration using Xorg.0.log. I was also able to turn of all composition in kde with a single click, but I don't see this option anymore.

Any help would be appreciated. Thanks for all the help and sorry for being so out-of-date on the latest and greatest in linux.

Shift-Alt-F12 disables compositing but it would be nice if someone could respond to my original email so that I can learn how to debug this issue. (Teach a man how to fish.)

I experienced probably the same problems after a d-u few weeks ago but also with ivy-bridge graphics card

I was alone with that problem, also didn't find similar reports via google. Workaround for me was to run the kernel i used before that d-u.

btw. you have run do journalctl as root

gerd,

Thanks for confirming that the problem exists.

I did run journalctl as root and get the same result:

Code Select

# journalctl 
No journal files were found.
-- No entries --

please have a look at http://manual.siduction.org/sys-admin-systemd#journalctl (http://manual.siduction.org/sys-admin-systemd#journalctl)

jure,

Thanks. I had read the manual. Please note that journalctl doesn't work even as root.

I believe that the journal process is not running as:

Code Select

# systemctl status systemd-journald.service
Failed to get properties: No such interface ''

Can someone help me debug?

I have solved the journalctl issue. Apparently something was wrong with systemd. I re-installed systemd and things are working.
