This is possibly a kernel DRM/RADEON/KMS bug, but it manifests itself only,
when plymouth does something new. How to disable what the phymouth is doing?
Description of problem:
Booting to lattest kernel packages has altered my display to a very large
text console (I am semi thankful of idea), but then latter the X will not
start telling only that it opened DRM successfully, but nothing more seems
to happen. (SysReq keys work, so I can do controlled reboot.)
Recent kernel package which does not enlarge the display is able to boot
with absolutely lattest xorg server.
Version-Release number of selected component (if applicable):
Failing one: initrd-generic-2.6.31-0.203.rc8.git2.fc12.x86_64.img
Correct function: initrd-generic-2.6.31-0.125.4.2.rc5.git2.fc12.x86_64.img
It did begin to fail soon after 0.125, but I don't remember when.
To use X on my workstation, I have to stick on 0.125 kernel.
Steps to Reproduce:
1. Boot to text console at first (I have never trusted those fools that
want to boot directly to X... I do understand it, but never trust.)
2. Have a large graphics panel and ATI Radeon HD 2600 XT card (+AMD x86_64)
(II) RADEON(0): Monitor name: BenQ 241W Z
(II) RADEON(0): Panel infos found from DDC detailed: 1920x1200
3. Start the X manually from your non-root account: startx &
4. Non-functioning system appears to clean the text screen, and leaves
the text mode on, never turning on the graphical mode.
Xorg.0.log sows following at its end. Full log file is at the attachment.
(II) Primary Device is: PCI 01@00:00:0
(II) [KMS] Kernel modesetting enabled.
(**) RADEON(0): Depth 24, (--) framebuffer bpp 32
(II) RADEON(0): Pixel depth = 24 bits stored in 4 bytes (32 bpp pixmaps)
(==) RADEON(0): Default visual is TrueColor
(**) RADEON(0): Option "accel" "on"
(**) RADEON(0): Option "AccelMethod" "shadowfb"
(**) RADEON(0): Option "DRI" "off"
(==) RADEON(0): RGB weight 888
(II) RADEON(0): Using 8 bits per RGB (8 bit DAC)
(--) RADEON(0): Chipset: "ATI Radeon HD 2600 XT" (ChipID = 0x9588)
(II) RADEON(0): PCIE card detected
(II) RADEON(0): KMS Color Tiling: disabled
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 11, (OK)
Looks like recent kernel (2.6.31-12.fc12.x86_64) and Xorg server are able to start X server from large text console, and upon X server shutdown also to return to large text display.
Something has been done either in initrd, or in X. Now X can start.
