blank screen during boot up when setting vga=795
Hi,
I have disabled the splash screen - which worked fine by editing the /boot/grub/menu.lst file removing reference to splash. However this leaves very large blurry 640x480 terminal text during boot up and or when exiting to tty. So the kernel line has quiet and splash removed and vga=795 put in. 795 is the code for 24-bit 1280x1024. kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=e870d1a9-e118-459c-8f23-903daa9f4b98 ro vga=795 Upon reboot - only see blank screen before login. I also tried 794, 791 (1024x768) but all made no difference. I have a Nvidia GT7600 Ubuntu 7.10 (kernel 2.6.22-14) The above follows the official guidelines, ie just need to add vga=xxx. Tried this suggestion - but upon reboot - no joy. 1. sudo vi /etc/initramfs-tools/modules and add fbcon and vesafb so my /etc/initramfs-tools/modules looks like: fbcon vesafb 2. sudo update-initramfs -u 3. sudo vi /etc/modprobe.d/blacklist-framebuffer 4. change the line "blacklist vesafb" to "# blacklist vesafb" Anyone get this working? |
The 'official guidelines' to which you refer *includes* quiet and splash along with the 'vga=795'. In other words, 'quiet splash' and 'vga=795' are inclusive; not exclusive.
Try adding quiet and splash along with vga=795 to see if that works. |

No Joy
Hi,
After trying again. No display on screen before standard ubuntu login screen. This is the same if, logged into gnome ubuntu itself, I try the tty (under ctil+alt+2..).. a blank screen. that kernel line again: Code:
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=e870d1a9-e118-459c-8f23-903daa9f4b98 ro quiet vga=795 |
I've just checked all three of my distro installations, in re splash, with the following result:
Knoppix: no reference to splash or quiet, but there is a vga= line. On boot, the default seems to be a verbose display of boot messages. Suse: no reference to quiet. Splash=verbose and vga= are present. PCLinuxOS: no reference to quiet. Splash=verbose and vga= are present. So, i suggest you try changing the syntax in the kernel line to something like 'splash=silent vga=795', and remove the 'quiet' entry. If you want to see the boot messages, use 'splash=verbose'. |
Hey, I got something on the start now. The verbose at least lists the start up actions in a small window under the ubuntu logo. The vga line doesn't seem to doing anything for the resolution though. This is confirmed after logging into Ubuntu. Ie, I still see a blank screen when accessing one of tty's (vga=795). My lcd is 1280x1024.
Code:
kernel /boot/vmlinuz-2.6.22-14-generic root=UUID=e870d1a9-e118-459c-8f23-903daa9f4b98 ro splash=verbose vga=795 |
Did you try simply "vga=normal"?
