Some years ago I was experiencing Xorg crashing and the "GPU HANG" problem seen in dmesg. These kernel parameters helped with that problem: intel_iommu=igfx_off i915.modeset=1 i915.enable_dc=0 i915.enable_fbc=1 i915.enable_psr=1 i915.enable_dp_mst=0 i915.disable_power_well=0 YMMV etc, Aki On 2024-01-27 19:58, R.

More importantly, I use it to constantly annoy Windows users, as proof that Linux helps you avoid electronic waste and costly laptop upgrades, because Linux is much better etc. (you know, the full programme). Fortunately, I noticed before I lose face that Linux wasn't working well anymore. Are you guys failing me now??? Impossible! Anyway, it's a funny problem indeed. I noticed that opening the properties of a package in Synaptic completely and immediately crashes the whole desktop and takes you back to the logon page. I thought the reason is that Synaptic runs as root, because running it as a normal user is fine. But then I started Synaptic over a remote x2go desktop as root, and it is fine there too. Later on, I saw that starting glxgears as a normal user on the local monitor (not over x2go) also triggers the whole desktop crash. By the way, glxgears does not run over x2go, I get "Error: couldn't get an RGB, Double-buffered visual". I tried the usual trick of prepending LIBGL_ALWAYS_SOFTWARE=true to Synaptic and glxgears, but it does not help, and neither does setting LIBGL_DRI2_DISABLE=true or LIBGL_DRI3_DISABLE=true. I also tried disabling the desktop compositing by choosing "Marco (No compositor)" in MATE Tweak, to no avail. I turns out that /usr/lib/xorg/Xorg is crashing. I managed to get the call stack, see at the bottom of this text. The key error in there "GLSL compile failure". Unfortunately, I don't know much about the X.Org Server or Mesa in order to pin-point the exact cause. I hope you guys can help me, as I not only wanted to keep annoying Windows users, but I was planning to extend my campaign to Mac users too. I am sure you can relate. All the best, rdiez Version information: The laptop is a Toshiba Satellite Pro C660 2N2 with an Intel Core i3 CPU M 380 @ 2.53GHz. The chipset is a Mobile Intel HM55 Express. I am running Ubuntu MATE 22.04.3. Ubuntu package libglapi-mesa version: 23.0.4-0ubuntu1~22.04.1 xdriinfo reports driver 'crocus'.</div> </blockquote> </body></html>
