Thread: Increase monitor resolution

as issue karmic users thought of writing this, hope guys.

first open terminal

applications >> accesories >> terminal

in terminal type :
1)

code:

 $ xrandr

(without $ mark)
display allowed resolutions
:

screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
vga1 connected 800x600+0+0 (normal left inverted right x axis y axis) 267mm x 200mm
800x600 85.1* +
640x480 75.0 60.0
720x400 70.1

then type
2)

code:

 $ cvt 1024 768

(any resolution want similar this)

output similar :

# 1024x768 59.92 hz (cvt 0.79m3) hsync: 47.82 khz; pclk: 63.50 mhz
modeline "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync

3)

code:

 $ xrandr --newmode <modeline>

(copy modeline of previous output place mode line)
example :

code:

$ xrandr --newmode "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync

4)

code:

$ xrandr --addmode vga1 1024x768_60.00

(here vga1 have use ever there for $ xrandr output in step 1)

5)

code:

 $xrandr --output vga1 --mode 1024x768_60.00 

(replace vga1 accordingly, remember use numbers within inverted commas in step 3 , after --newmode 1024x768_60.00 )

***running these change resolution temporary.these steps done make sure these commands work . after step 5 should see resolution change.if successful proceed next step


6)

code:

$ sudo gedit /etc/gdm/init/default

(this ask root password type password , text editor appear)
in see text line

path=/usr/bin:$path
old_ifs=$ifs

just below paste the step 3 5 commands
, save it.

example :

#!/bin/sh
# stolen debian kdm setup, aren't sneaky
# plus lot of fun stuff added
# -george

path=/usr/bin:$path
old_ifs=$ifs
xrandr --newmode "1024x768" 70.00 1024 1072 1176 1328 768 771 775 798 -hsync +vsync

xrandr --addmode vga1 1024x768_60.00

xrandr --output vga1 --mode 1024x768

if [ -x '/usr/bin/xsplash' ];

then
/usr/bin/xsplash --gdm-session --daemon

this worked in karmic ......i think helpful if want know more xrandr

if step 6 isn't working read post mpatrick

thanks!
