Hello
I am trying to use the Ubuntu 9.10-based BitDefender Rescue Disk on USB and CDROM on two different hosts, and am having the following issues:
1. On an Acer Aspire L100 desktop with an "Integrated NVIDIA® GeForce® 6150 graphics", I can't get better than 800x600, which is too low for the BitDefender application to run (complains about the definition being too low).
I tried the following, to no avail:
# 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
2. On the other host, which is an Acer 3810 laptop, although I selected French as the language to be used when prompted by BitDefender at boot-time, the layout is US, but I can't get it to work in French. I tried both commands in a terminal window:
# loadkeys fr
"Cannot open display "default display"".
# setxkbmap fr
"Cannot open display "default display"".
FWIW, hosts and monitors support 1024x768@75Hz under Windows after installing the required driver.
Any idea what I could try?
Thank you.

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.

For those having the same issue: It might be distro-dependent, but on the liveCD I'm using, "setxkbmap" can only run as non-root. OTOH, "loadkeys" can only run as root.
