The video and sound stopped. - Keyboard was unresponsive, can't get into console, and for example pressing caps lock/num lock didn't toggle keyboard leds. - mouse didn't move. - The whole computer and OS didn't crash I suppose. I could ping the computer from another computer. and there were entries in /var/log/syslog after the GUI freeze. What ever happened I can find some indicating in /var/log/syslog: Crash happened 14:21 local time which pinpoints the bug into these entries: Jul 16 14:21:24 Aorus-Ultra-Ryzen gnome-shell[897367]: [Child 897367, ImageBridgeChld] WARNING: failed to open shm: Too many open files: file /build/firefox-k3d8Rk/firefox-78.0.2+build2/ipc/chromium/src/base/shared_memory_posix.cc, line 246 Jul 16 14:21:24 Aorus-Ultra-Ryzen gnome-shell[897367]: [Child 897367, MediaDecoderStateMachine #1] WARNING: Decoder=7f08246e5000 Decode error: NS_ERROR_OUT_OF_MEMORY (0x8007000e) - mozilla::MediaResult mozilla::FFmpegVideoDecoder<46465650>::CreateImage(int64_t, int64_t, int64_t, MediaDataDecoder::DecodedData &): image allocation error: file /build/firefox-k3d8Rk/firefox-78.0.2+build2/dom/media/MediaDecoderStateMachine.cpp, line 3470 Jul 16 14:21:25 Aorus-Ultra-Ryzen gnome-shell[897367]: message repeated 2 times: [ [Child 897367, MediaDecoderStateMachine #1] WARNING: Decoder=7f08246e5000 Decode error: NS_ERROR_OUT_OF_MEMORY (0x8007000e) - mozilla::MediaResult mozilla::FFmpegVideoDecoder<46465650>::CreateImage(int64_t, int64_t, int64_t, MediaDataDecoder::DecodedData &): image allocation error: file /build/firefox-k3d8Rk/firefox-78.0.2+build2/dom/media/MediaDecoderStateMachine.cpp, line 3470] after that anything GUI, keyboard or mouse related was totally unresponsive. there were other entries in syslog after that, and ping worked into this frozen machine. So the whole OS didn't crash. Only GUI related. I hope this helps. lsb_release -rd Description: Ubuntu 20.04 LTS Release: 20.04 apt-cache policy firefox firefox: Installed: 78.0.2+build2-0ubuntu0.20.04.1 Candidate: 78.0.2+build2-0ubuntu0.20.04.1 Version table: *** 78.0.2+build2-0ubuntu0.20.04.1 500 500 http://fi.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages 100 /var/lib/dpkg/status 75.0+build3-0ubuntu1 500 500 http://fi.archive.ubuntu.com/ubuntu focal/main amd64 Packages I'm sure this is a bug.
