Just guessing that this is a kernel driver bug rather than an X bug, hence the kernel component selected. When the login manager tries to load, all that ultimately paints is the background graphic. WINDOWMANAGER=/usr/bin/icewm startx produces a black screen with mouse pointer. Xorg.0.log shows no apparent problem. No apparent difference whether using kernel 5.9.10 or 5.8.15. Vttys work as expected. Replacing the Radeon AGP rv250 ID: 1002:4c66 gfxcard with a Matrox G400 makes X work entirely as expected. # inxi -Ca CPU: Info: Single Core model: Pentium III (Coppermine) socket: Slot-1 bits: 32 type: MCP arch: P6 III Coppermine family: 6 model-id: 8 stepping: 1 microcode: D L1 cache: 16 KiB L2 cache: 256 KiB flags: pae sse bogomips: 1403 Speed: 702 MHz min/max: N/A base/boost: 700/850 volts: 3.3 V ext-clock: 100 MHz Core speed (MHz): 1: 702 Vulnerabilities: Type: itlb_multihit status: KVM: VMX unsupported Type: l1tf status: Vulnerable Type: mds status: Vulnerable: Clear CPU buffers attempted, no microcode; SMT disabled Type: meltdown status: Vulnerable Type: spec_store_bypass status: Vulnerable Type: spectre_v1 mitigation: usercopy/swapgs barriers and __user pointer sanitization Type: spectre_v2 mitigation: Full generic retpoline, STIBP: disabled, RSB filling Type: srbds status: Not affected Type: tsx_async_abort status: Not affected # inxi -GISMy System: Host: s2846 Kernel: 5.8.15-1-default i686 bits: 32 Console: tty 3 Distro: openSUSE Tumbleweed 20201127 Machine: Type: Desktop Mobo: Tyan model: Intel 440BX/GX v: Rev. 4 serial: 00000000 BIOS: American Megatrends v: 063101 date: 07/15/99 Graphics: Device-1: AMD RV250/M9 GL [Mobility FireGL 9000/Radeon 9000] driver: radeon v: kernel Display: server: X.org 1.20.9 driver: ati,radeon unloaded: fbdev,modesetting,vesa tty: 180x56 Message: Advanced graphics data unavailable in console for root.
