Bug#784738: installation-reports: [ppc] PowerBook3,5 (G4 15" Titanium): backlight turns off during installation
Package: installation-reports
Severity: normal
On my old Powerbook G4, installation proceeds normally until I have left
the machine downloading and installing GNOME (which takes a while), at
which point the backlight turns off. Keyboard activity does not reactivate it.
The screen remains active, but cannot be read: by shining a sufficiently
bright light (phone camera LED) through the Apple logo on the back of
the screen, I can see that the progress bar continues to move, but
this does not illuminate enough of the screen to answer subsequent
questions.
Workaround: boot in expert mode, load the network console udeb,
bring up networking and do the rest of the installation over ssh.
Non-workarounds (tried without success):
* use the keyboard
* Ctrl+Alt+F1
* echo 0 > /sys/class/graphics/fb0/blank (via ssh)
* echo 0 > /sys/class/graphics/fb1/blank (via ssh)
In the installed system (with X, pbbuttonsd, etc. - I used the GNOME
desktop task, and later added lightdm and task-lxde), the backlight
*is* switched back on by keyboard activity, and can also be
controlled via Fn+F1/Fn+F2.
Other misc hardware-specific notes:
* In debian-installer on the laptop screen, red and blue seem to be
reversed: the screen background is red, the window title
is blue, and the highlight for the active item in a menu is blue.
The network console (ssh) behaves like x86: blue background,
grey window with red title, red highlight. (An endianness bug?)
* lightdm and lxde work, but are unstable (X sometimes locks up) with
default settings; running OpenArena reliably locks up X.
Workaround: add "radeon.agpmode=-1" to the kernel command-line
in /etc/yaboot.conf, and run ybin.
* GNOME 3's hardware acceleration check does not detect the ATI Radeon
as valid hardware acceleration for GNOME Shell, so gdm and gnome-session
do not work ("oh no! something has gone wrong") even with
radeon.agpmode=-1; this seems to be somewhat deliberate, since
/usr/share/gnome-session/hardware-compatibility lists "Pre-R300 radeon"
as blacklisted, and this Radeon is a R250. Workaround:
use something designed closer to the laptop's era.
* Sound card is not detected, https://bugs.debian.org/714345
* Plymouth works (!) but the colours are off: the Lines theme has a
blue-purple blend instead of blue-teal. (Possibly an endianness
bug reversing the red and green channels?)
All in all, not bad for a more than decade-old laptop :-)
