The kernel is then loaded, and initially uses a display mode of 80x25 text rather than 1024x768 or 1280x800. [ 0.000000] vt handoff: transparent VT on vt#7 [ 0.000000] Console: colour VGA+ 80x25 [ 0.000000] console [tty0] enabled Subsequently, drm/radeondrmfb is initialised, and the console switches to 160x50 text: [ 3.000866] [drm] fb mappable at 0xD0141000 [ 3.000870] [drm] vram apper at 0xD0000000 [ 3.000872] [drm] size 4096000 [ 3.000873] [drm] fb depth is 24 [ 3.000875] [drm] pitch is 5120 [ 3.473151] Console: switching to colour frame buffer device 160x50 [ 3.476071] fb0: radeondrmfb frame buffer device [ 3.476073] drm: registered panic notifier [ 3.476085] [drm] Initialized radeon 2.8.0 20080528 for 0000:01:00.0 on minor 0 For some reason, the mode isn't properly set to 1280x800, and so the plymouth log contains entries like those below (I've attached the full debug log). This is especially annoying, as when the console switches to 160x50 from 80x25, because the screen geometry is now effectively four times larger, the plymouth text splash is reduced to the upper left quarter of the console. This is a regression, because plymouth worked beautifully in maverick, and also worked at the beginning of this cycle for a while; I cannot remember the software versions/packages that caused the regression.
