Change Resolution To 1024x768?

Hello

Using the default settings, the Rescue Disk starts in 800x600 and complains that the resolution is too low to run the app in graphic mode.

FYI, this servers + monitor run Windows just fine in 1024x768 @ 75Hz, and even higher.

I tried adding "screen=1024x768" to the command-line, to no avail.

FWIW, the default includes "vga=791" but I don't know what it means.

If someone had the same issue, how can I set the resolution to something higher so I can run BitDefender in graphic mode?

Thank you.

Not gettting any luck. It seems like BitDefender doesn't like the "Integrated NVIDIA® GeForce® 6150 graphics" included in the Acer Aspire L100, and won't let users change the video settings:

# gtf 1024 768 75

# 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz
Modeline "1024x768_75.00"  81.80  1024 1080 1192 1360  768 769 772 802  -HSync +Vsync

# xrandr --newmode "1024x768_75.00"  81.80  1024 1080 1192 1360  768 769 772 802  -HSync +Vsync
Can't open display

More progress... leading nowhere:

# echo $DISPLAY
:0.0

# xhost +localhost
No protocol specified
xhost:  unable to open display ":0.0"

Read that on Debian/Ubuntu, by default, X is configured with "-nolisten tcp":

# ps aux | grep X | grep -v grep
root      2477  0.1  1.7  23552 17056 tty7     Ss+  16:37   0:06
/usr/bin/X11/X -nolisten tcp -auth /var/run/slim.auth vt07

So looked for configuration file...

# find / -name "gdm*"
/etc/gdm
/var/lib/update-rc.d/gdm
/rofs/etc/gdm
/rofs/var/lib/update-rc.d/gdm

# gdmsetup
Command not found

Edited /etc/gdm/custom.conf to add this:

[Security]
DisallowTCP=false

Logged off, logged back on (this live CD is not persistent, so can't reboot and keep settings):

# xhost +localhost
xhost:  unable to open display ":0.0"

Were there major changes in Ubuntu 9.10 that would explain this permission issue + missing configuration files?

Thank you.

Got the same message with the latest version, downloaded 8/23, on a Dell workstation, but then it ran just fine anyway ??

Thanks Chris for the tip.

Found what it was: For Nvidia-based hosts, the BitDefender CD uses the Nv video driver (xserver-xorg-video-nv), but this driver is deprecated and doesn't work well with the host I have.

The solution is to uninstall Nv, and install either its open-source successor Nouveau, or Nvidia's closed-source binary drivers.

I'm trying to figure out how to update the ISO with the latest package of everything and burn a new CD, so that it'll work OK on Nvidia-based hosts. No idea if other video chipsets are also problematic.
