1 Hi,
2
3 I am using a NVIDrIA-card GeForce 7600 GT with vanilla 2.6.27.12 linux
4 kernel and grub boot loader.
5 The commandline to boot the kernel is:
6 kernel (hd0,0)/vmlinuz-2627012 rootfstpye=reiserfs root=/dev/sda3 ro vga=31B.
7
8 This works like a charm...but the resulting resolution a little too
9 high.
10 So I replaced "vga=31B" with "vga=ask" and after rebooting press
11 RETURN to see all available modes. I replaced "vga=31B" with "vga=317"
12 (both were VESA modes, if I rember correctly.
13 After rebooting, the screen remains black as long as X were started.
14
15 Why does "vga=31B" does work and "vga=317" does not despite the fact
16 both were reported as working modes by grub.
17
18 Ah! By the way: Interrupting grub, and editing the commandline for
19 the kernel boot and setting "vga=317" _by hand_ works like a
20 charm.
21
22 Any help will be very appreciated.
