The relevant bits of the log here are: [ 53814.484] (--) PCI:*(0@0:2:0) 1013:00b8:1af4:1100 rev 0, Mem @ 0xfc000000/33554432, 0xfebd0000/4096, BIOS @ 0x????????/65536 This says your "video card" is the kind of Cirrus Logic GD-5446 that qemu happens to have an emulator for. Which was not a great card even when it was new, which was 1995. Then: [ 53814.487] (II) Loading /usr/local/lib/xorg/modules/drivers/vesa_drv.so [ 53814.487] (II) Module vesa: vendor="X.Org Foundation" [ 53814.487] compiled for 1.20.8, module version = 2.4.0 Version 2.4.0 of the vesa driver is fairly old, but there isn't a new version released yet. That's my fault, and here it would have saved you some pain, because there's a bugfix since 2.4 that avoids the next problem: [ 53814.496] (EE) VESA(0): Specified fbbpp (24) is not a permitted value The vesa driver tries to use a depth-24 framebuffer if possible. However, the pathetic cirrus card that qemu emulates only supports depth 24 at 24 bits per pixel, instead of the much more common and performant 32 bits per pixel. Starting with xserver 1.20 the software renderer no longer supports drawing to a 24bpp framebuffer, so when vesa says "please use 24bpp it's all I have" the server says "nope" and you crash. I'll push out a new vesa driver release, since the current code in git has a fix for this situation where it will use 16bpp instead. But I strongly suggest you use literally any other emulated video card, and not wait for the new driver release, because - again - the cirrus card being emulated here is Not Good. If you're using qemu directly, saying '-vga std' instead of cirrus will get you a much nicer basic graphics experience than '-vga cirrus'. If you're using virt-manager or similar you can configure this through the UI. - ajax _______________________________________________ [email protected]: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
