The Xorg freeze with blender I reported in the first message of this thread seems to be a different issue. I could run top(1) accessing from another machine using SSH. I pasted the results at bottom, as you see, contrary to what happens with the stress command, now CPUs are totally idle. I could even kill blender but the screen was still frozen, the only responsive was the mouse movement. The I could kill cwm(1), but when I finally tried to kill Xorg the whole system froze.
This bug must be related to opengl, since changing to vulkan in the configuration it does not happen. I didn't described step by step how to reproduce it in my first post because the cube that appears by default in the scene is not enough to accomplish it. I think that the blender feature that produces the hang is the sky texture in Word. Now I'll share a test file for whoever wants to make the test in their machines. https://en.roquesor.com/Downloads/blender_test.tar.gz Once uncompressed, in the directory you'll find a *.blend file. I guess many of you don't know how to use blender so, first some basic concepts. When you open blender the first time, the scene you are presented is a cube, a light and a camera, the window containing the scene is called a "viewport". At first the objects are represented in grey, this is the "solid view", to reproduce the freeze you need to change to "render view", you can do this by clicking on the first icon at the top right corner of the viewport. I include a screenshot in the tarball indicating which is the icon. Once in render view, at least in my case, I just need to play a bit zooming in and out a couple of times to freeze Xorg. $ top -S load averages: 0.07, 0.04, 0.03 chancha.roquesor.com 08:49:28 114 processes: 106 idle, 8 on processor up 0 days 12:53:55 CPU0: 0.0% user, 0.0% nice, 0.4% sys, 0.0% spin, 0.0% intr, 99.6% idle CPU2: 0.0% user, 0.0% nice, 0.0% sys, 0.0% spin, 0.0% intr, 100% idle CPU4: 0.0% user, 0.0% nice, 0.0% sys, 0.0% spin, 0.0% intr, 100% idle CPU6: 0.0% user, 0.0% nice, 0.0% sys, 0.0% spin, 0.0% intr, 100% idle Memory: Real: 1059M/24G act/tot Free: 6608M Cache: 20G Swap: 0K/32G PID USERNAME PRI NICE SIZE RES STATE WAIT TIME CPU COMMAND 3273 root 10 0 0K 13M sleep/2 bored 0:20 0.05% drmtskl 66178 root 28 0 0K 13M onproc/6 - 770:37 0.00% idle6 44484 root -22 0 0K 13M sleep/0 - 770:11 0.00% idle0 16500 root 28 0 0K 13M onproc/4 - 769:15 0.00% idle4 75208 root 28 0 0K 13M onproc/2 - 768:46 0.00% idle2 4112 root 28 0 0K 13M onproc/1 - 112:37 0.00% idle1 90120 root 28 0 0K 13M onproc/3 - 112:37 0.00% idle3 96051 root 28 0 0K 13M onproc/5 - 112:37 0.00% idle5 51024 root 28 0 0K 13M onproc/7 - 112:37 0.00% idle7 72881 root 10 0 0K 13M idle bored 0:22 0.00% i915 97930 root 10 0 0K 13M sleep/0 bored 0:21 0.00% softnet0 68610 morlock -22 0 55M 91M idle schto 0:20 0.00% Xorg 60645 morlock 2 0 1046M 1158M idle kqread 0:10 0.00% blender-bin 34724 root 10 0 0K 13M sleep/0 bored 0:06 0.00% i915-unorde 8732 root 10 0 0K 13M sleep/0 bored 0:05 0.00% sensors 81300 root 10 0 0K 13M sleep/0 bored 0:02 0.00% systqmp 26818 root -22 0 0K 13M sleep/0 tmoslp 0:02 0.00% softclockmp 17271 root 105 20 0K 13M idle pgzero 0:01 0.00% zerothread 8618 root 10 0 0K 13M sleep/0 acpi0 0:01 0.00% acpi0 $ systat 3 users Load 0.00 0.02 0.03 chancha.roquesor.co 08:47:34 memory totals (in KB) PAGING SWAPPING Interrupts real virtual free in out in out 970 total Active 1085788 1085788 6765040 ops inteldrm All 25482540 25482540 40300836 pages nvme0 1 xhci0 Proc:r d s w Csw Trp Sys Int Sof Flt forks iwx0 140 226 23 3 101 6 fkppw ahci0 fksvm azalia0 0.0%Int 0.0%Spn 0.1%Sys 0.0%Usr 99.9%Idle pwait 1 em0 | | | | | | | | | | | relck pckbc0 norlk pckbc0 noram 968 clock Namei Sys-cache Proc-cache No-cache ndcpy ipi Calls hits % hits % miss % fltcp zfod cow Disks sd0 sd1 268729 fmin seeks 358305 ftarg xfers 448837 itarg speed 1K 231699 wired sec 0.0 pdfre pdscn pzidl 1 IPKTS 18 kmape OPKTS -- Walter
