[Bug 1186365] New: Empty screen on Live XFCE in QEMU with virgl
http://bugzilla.opensuse.org/show_bug.cgi?id=1186365 Bug ID: 1186365 Summary: Empty screen on Live XFCE in QEMU with virgl Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Xfce Assignee: bnc-team-xfce@forge.provo.novell.com Reporter: arvidjaar@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I observed this both with Leap 15.3 current image and with Tumbleweed. I boot manually using "${QEMU_BIN}" \ -nodefaults \ -machine q35,accel=kvm \ -cpu kvm64 \ -m 2G \ -device virtio-scsi-pci \ -drive file=$HOME/tmp/openSUSE-Leap-15.3-XFCE-Live-x86_64-Build9.78-Media.iso,if=none,id=cd0,format=raw -device scsi-cd,drive=cd0,id=cd0 \ -netdev user,id=uplink -device virtio-net-pci,netdev=uplink \ -name "Leap 15.3 Live XFCE" \ -monitor unix:path="$QEMU_MONITOR_SOCKET",server=on,wait=off \ -vga virtio -display gtk,gl=on,zoom-to-fit=off,show-cursor=on \ & It boots and leaves me with empty screen. Switching to tty1 and logging in I see full graphical session correctly started, all processes present, just no output on tty7. This works if I disable OpenGL (-display gtk,gl=off). The KDE Live image boots normally using the same command line. TW XFCE Live image has the same issue. Regular TW GNOME and KDE both work with virgl. Host - Ubuntu 20.04 with GNOME Wayland session. QEMU emulator version 6.0.0 (v6.0.0-1-gd11fb9fde1) virglrenderer-0.7.0-1138-g3639155 Both compiled from source. QEMU has single patch to fix mouse positioning in gtk under Wayland. -- You are receiving this mail because: You are on the CC list for the bug.

Sounds like the display manager (or maybe X itself) selects the wrong VT.
1. If I disable auto-login I get lightdm greeter, I enter my user name and password and then I get blank screen (while session is completely launched). 2. I installed GNOME/X11 and if I select gnome X11 session in lightdm, I get normal fully functional GNOME desktop. 3. I still get blank screen if I log out of GNOME and log in into Xfce again. So it is really Xfce issue and it looks like some OpenGL/HW acceleration/whatever is missing in Xfce. But I am not familiar with it deep enough to even start digging. If anyone has any idea where to look ... -- You are receiving this mail because: You are on the CC list for the bug.

Xfwm4 4.18.0 does not have this issue. Commit itself is pretty trivial and should be easily backportable. -- You are receiving this mail because: You are on the CC list for the bug.
