Depending on the size and/or resolution of your screen you can add a vga=XXX cheat code to your kernel line during boot. If you want to make it permanent, add it to the kernel line in you grub conf. This link explains a bit:
http://www.damnsmalllinux.org/wiki/index.php/Vga%3Dxxx
BTW - vga=791 or 792 has worked on normal size monitors for me. See different resolutions in the link.0 -

xrandr talks to the x11 subsystem, it should work on all Linux based distros without root rights. The command to change it on your system should be
xrandr --output VGA1 --size 1024x768

When i use command get this error in ubuntu.
hoseini@hoseini-HP:~$ xrandr --output VGA1 --size 1024x768
xrandr: Failed to get size of gamma for output default
warning: output VGA1 not found; ignoring0 -
If you just run the xrandr command without any arguments it will show what displays are connected. You can replace vga1 with the designation of your connected monitor.0

I dont know what is VGA1 replacement.0 -
that is an interesting output, what I got from xrandr without arguments is:
matt:~$xrandr Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 1366x768 60.0*+ 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) TV1 disconnected (normal left inverted right x axis y axis)
in my case LVDS1 is my laptop monitor. I am thinking that you have a single connection, which I have not dealt with before.
Have you tried running "xrandr --size 1024x768" to see if it will automatically push to your default display?0 -
thanks.I use this command and work for me. (xrandr --size 1024x76)
But I want to khow that there is any command for changing resolution.0 -
the xrandr command is used to change resolution via the command line. Can you please explain exactly what else you are looking to accomplish?0
-
I mean I can change resolution just with these two commands or no we have more commands.0
-
I do not know of another cli based command that changes the x11 display properties, however xrandr has plenty of options which you can combine to get your desired video configuration. you can view the manual page at http://www.manpagez.com/man/1/xrandr/ to review the other options.0

From the xrandr manual:xrandr - primitive command line interface to RandR extension
There might be another programan that works with RandR but I know no other in the command line.0 -
my english is very bad, but i think:
change your xorg.conf
edit this file and you can see this, roughly:Section "Screen" Identifier "Default Screen" Device "ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]" Monitor "Monitor genérico" DefaultDepth 24 SubSection "Display" Depth 1 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 4 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 8 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 15 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 16 Modes "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Depth 24 Modes "1024x768" "800x600" "640x480" EndSubSection EndSection
and then you only chage the eight line, only add "1280x800"
and your new file is it:Section "Screen" Identifier "Default Screen" Device "ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]" Monitor "Monitor genérico" DefaultDepth 24 SubSection "Display" Depth 1 Modes [u] [b]"1280x800"[/b] [/u]"1024x768" "800x600" "640x480" . . . .
