Hi!

I'm facing two issues on 13.1+Tumbleweed where I'm not sure whether they are connected to each other or not.

1. Sometimes my screen contains flickering fragments. Mostly within Firefox and Thunderbird, never in QT/KDE-Applications It looks like old screen contents pop up.

2. After resuming from suspend2ram I can move the cursor but the screen does not get updated. I see the old screensaver image but it does not get updated nor a login prompt pops up. If I change to tty1 and kill kwin the screensaver continues and I get a login prompt where I can login. Now the interesting part, if I start kwin again in this recovered KDE-Session the screen freezes again and I can still only move the cursor.

All this happens on my Thinkpad T430u. GPU: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device 500c Flags: bus master, fast devsel, latency 0, IRQ 43 Memory at f0000000 (64-bit, non-prefetchable) [size=4M] Memory at e0000000 (64-bit, prefetchable) [size=256M] I/O ports at 5000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915

Are these issues known? How to debug further? So far I did not spot anything of interest in my logs.

Hi, what acceleration do you use? UXA or SNA? (Try to switch to the other.)

After switching to UXA all my problems as gone. :) Did xf86-video-intel move to SNA by default? -- Thanks, //richard -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

That would be an actual kernel bug that needs to be fixed...if still happens with kernel:stable and/or kernel:head report it to the intel-gfx development list. -- Cristian "I don't know the key to success, but the key to failure is trying to please everybody." -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Hm, for me (using gdm for logging into an XFCE session), just changing to VT1 and back to VT7 fixes the artifacts.

Had some time to play again with the issue. Besides Tumbleweed I had also the Xorg report enabled. Now on 13.1 without Xorg repo everything works fine. UXA and SNA. If I use the X packages from the Xorg repo only UXA seems to work. But there is still another (now) issue. If I unplug my external screen X is crashing. As soon I can find more time I'll try to get more details and report a bug. Sadly this is my main laptop used for work I cannot break it all day long. :-)

That makes sense. I'm using Factory with the Xorg repo and I'm seeing the flickering in Mozilla software heavily as well. It looks like backbuffer and frontbuffer would have different states of the stuff to display and we'd constantly flip between them (i.e. one has the previous state and one has the current state), or something like that.

I *think* it started happening when Mesa was updated in the Xorg repo recently. I know it still did work when I already had X.org 1.1.5.99 from there, so X server itself isn't it. It started pretty recently, but I'm not sure if there was a significant Intel driver update or only the Mesa update that was larger. Of course, sometimes small patches can cause this as well and those repos constantly get smaller updates, I guess.

The problem is caused by xf86-video-intel-2.99.912 update, if you revert to xf86-video-intel-2.99.911 the problem will disappear. Cheers, ConteZero -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Ah, awesome to know. Is there a bug report filed on the driver side? Do you have a link for that?

You might be better off grabbing one of 3.0git builds from the BS. I think this is already solved from what I've been seeing on the intel driver mailing list. -- "The wise are known for their understanding, and pleasant words are persuasive."
