Hi!
I've a toshiba satellite notebook, and I tried to install centos 5.6. The installer starts, but when it turns to graphical mode, the backlight goes off. I see the windows, buttons, but it's very dark, maybe the backlight switching off..
How can I get the installer to work correctly?
The machine details: core i3 330m (The graphics controller maybe integrated to the cpu...) it's a MHD4500 (GMA4500)
Thanks: Balazs

Ok, I did the text mode install successfully. The problem still exists: when i start X, or enter to runlevel 5, the screen goes to black. How can I resolve the problem? Is there any update, workaround?
Thanks: Balazs

Try rm /etc/X11/xorg.conf system-config-display

Ok, I rm the xorg.conf file. After I start immediately the X server, the screen was visible but only in 800x600 resolution. I tried to change it, but there is no other modes available.
So I get back to console and try s-c-d, then start again X. The backlight went off again, so I returned to the original problem.
I tried to manually edit the xorg.conf, but the result is the same blank screen.
I think that the problem is depending by the resolution.
Any clue?

Have you tried with nomodeset option in grub's kernel options? It helped me with my older Intel graphics on RHEL 6 Beta.

Hi.
I tried your advice, but still no luck.
my grub.conf: (menu.lst) default=0 timeout=0 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-238.12.1.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-238.12.1.el5 ro root=LABEL=/ nomodeset initrd /boot/initrd-2.6.18-238.12.1.el5.img
I erased the rhgb and quite flag.
The screen blank again. I write a xorg.conf, which seems to be ok, the resolution is 1360x768 for a 15,6" display. I think this is the max and correct.
Bye
