Bug#641181: [linux-2.6] black screen shortly after starting boot
Package: linux-2.6
Version: 3.0.0-3
Severity: normal
Hello,
I freshly installed wheezy with kernel linux 3.0.0-1-amd64 on my
Lenovo Thinkpad T400.
During boot, after the message "Waiting for /dev being fully populated"
is displayed, my screen turns first into flickery white lines
in the upper third of my screen and then (I bet after switching
to graphic mode) the screen is fully black. I tried several boot options
like "fb=false" and/or "vga= ..." with several modes but this didn't
helped. But my computer is running without screen because I can
remotely log in using ssh. Luckily, I installed the ssh-server during
installation.
During the boot of the installation CD-ROM I had no problems.
Now, strange thing: I was playing a bit around after remote log in
and it turned out, that after installing the package
"firmware-linux-nonfree"
from the non-free section, booting now works fine. I.e., I see all boot
messages,
it switches to framebuffer mode and also switching to graphical mode at
the end of the boot sequence works. Thus I can work with my laptop again.
Btw., I verified by another fresh installation, that I only need the
additional
package "firmware-linux-nonfree" from non-free.
My graphic hardware is (from lscpi -v):
01:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon
HD 3400 Series (prog-if 00 [VGA controller])
Subsystem: Lenovo Device 210e
Flags: bus master, fast devsel, latency 0, IRQ 48
Memory at d0000000 (32-bit, prefetchable) [size=256M]
I/O ports at 2000 [size=256]
Memory at cfff0000 (32-bit, non-prefetchable) [size=64K]
[virtual] Expansion ROM at cff00000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: fglrx_pci
remarks:
1. the Kernel driver "fglrx_pci" I installed later!
2. Also the (recovery mode) in the grub chooser showed the same behavior.
Bye
Ralf
