What exactly changed during the system update? In particular, which version of the kernel and xserver-xorg-video-radeon were you running before and afterwards? > Also, maybe another bug though, I tested to change "DefaultDepth 24", > to > 32. Depth 32 isn't supported by the radeon driver, as it can't make any use of the additional bits. Depth 24 uses 32 bits of storage for each pixel. > That apparently froze my system (afterward 100++ logfiles). That's a gdm3 bug, which should be fixed in gdm3 3.4. > [ 286.097] (II) RADEON(0): Output VGA-0 using monitor section JT198x4 [...] > [ 286.377] (II) RADEON(0): EDID for output VGA-0 > [ 286.377] (II) RADEON(0): Printing probed modes for output VGA-0 > [ 286.377] (II) RADEON(0): Modeline "1024x768"x60.0 65.00 1024 1048 1184 > 1344 768 771 777 806 -hsync -vsync (48.4 kHz e) > [ 286.377] (II) RADEON(0): Modeline "800x600"x60.3 40.00 800 840 968 > 1056 600 601 605 628 +hsync +vsync (37.9 kHz e) > [ 286.377] (II) RADEON(0): Modeline "800x600"x56.2 36.00 800 824 896 > 1024 600 601 603 625 +hsync +vsync (35.2 kHz e) > [ 286.377] (II) RADEON(0): Modeline "848x480"x60.0 33.75 848 864 976 > 1088 480 486 494 517 +hsync +vsync (31.0 kHz e) > [ 286.377] (II) RADEON(0): Modeline "640x480"x59.9 25.18 640 656 752 800 > 480 489 492 525 -hsync -vsync (31.5 kHz e) Looks like the monitor connected to the VGA output is providing an EDID specifying 1024x768 as the maximum resolution. You might be able to override this though, either by adding a ModeLine for "1280x1024" in Section "Monitor" or at runtime using the xrandr utility. > [ 286.626] (**) RADEON(0): Display dimensions: (1280, 1024) mm > [ 286.626] (**) RADEON(0): DPI set to (20, 19) Probably not directly related to your problem, but these are pretty weird settings you're specifying in xorg.conf...
