[SOLVED] xorg intermittent core dump since update to 1.19.1-1
Since the 1.19.1-1 update to xorg-server it's started dumping core on me intermittently (a couple of times a day). This is on a laptop with an external monitor, and it's possible that the core dump is happening when moving the pointer rapidly between the external monitor to the laptop panel, but that could easily be a coincidence. The laptop has both an Intel and an Nvidia GPU. I'm only using the Intel driver, but haven't completely removed all Nvidia support ... if that is the problem, it hasn't been up until now.
Beyond the trace in the journal I'm not seeing anything obvious ... there's nothing out of the ordinary in the Xorg.0.log. Has anyone else had a similar experience?
The trace is below ... any advice on how to diagnose this would be very much appreciated.

Really? What's the status of the built in support for Intel GPUs? Does it have feature parity with xf86-video-intel?

Re: [SOLVED] xorg intermittent core dump since update to 1.19.1-1
Yes I understand. It is a dead driver, that distro's are starting to abandon

Re: [SOLVED] xorg intermittent core dump since update to 1.19.1-1
OK, thanks ... I've dug into this a bit more and it does seem that xf86-video-intel has been abandoned.
Following your advice ... much appreciated.

I'd be interested in opinions on the pros and cons of xf86-video-intel vs. the built in modesetting driver. Are there any downsides to using the latter?

Only upside with intel that I can think of, is that you have the option to use the SNA 2d acceleration in X. It should be slightly faster but also buggier than "glamor" used by modesetting driver (you can also use glamor with intel driver though).
I've understood modesetting should be less cod, simpler design and more actively developed.
There shouldn't be any difference with 3d performance

Re: [SOLVED] xorg intermittent core dump since update to 1.19.1-1
I've switched over to the built in modesetting driver, and for the most part everything is fine. However I am seeing some flickering of the mouse pointer, towards the top edge of external monitor (which is my primary). This is fairly annoying, but preferable to core dumps. Does anyone have any pointers on fixing that? FTR, I've now blacklisted nouveau, so I'm only using the built in Intel GPU and driver.
Update: this only appears to be happening on the Chrome tab bar, and only when it's on the external monitor.
Update: I fixed the flicker by tweaking Chrome flags as described here.

Re: [SOLVED] xorg intermittent core dump since update to 1.19.1-1
I am having the same issues, got a Xorg core dump twice in 1 hour. Also uninstalled xf86-video-intel and haven't had a crash in the 7 hours since.
I have the exact same strack trace:

Re: [SOLVED] xorg intermittent core dump since update to 1.19.1-1
Hmm... had the same issue so I removed xf86-video-intel, which improved the general performance of rendering, but I'm using the i3 window manager and for some reason, without xf86-video-intel, status bars do not show (although i3bar is running). Has anybody else had an issue like that? I've looked around and don't see anyone reporting issues like this one. I had no xorg config for video, just removed the package.

I had the same issue, the name of the displays changed from DP1-1 to DP-1-1, DP2 to DP-2, etc.
Take a look at the output of xrandr.

Has anybody else had an issue like that? I've looked around and don't see anyone reporting issues like this one. I had no xorg config for video, just removed the package.
I had the same issue, the name of the displays changed from DP1-1 to DP-1-1, DP2 to DP-2, etc.
Take a look at the output of xrandr.
You are my hero! Thanks, working great now.
