Thread: Can't figure out how to add resolutions to nvidia x server settings program

i installed ubuntu 11.10 on new computer yesterday, , day i've been reading internet , trying higher resolution show option in 'nvidia x server settings' program, no, i'm stuck.

dual boot win7 has no troubles using same monitor @ 1600x1200@85hz same hardware, , old computer ubuntu using same monitor @ resolution & refresh rate.

in similar problems on forums, people asked this, here if case helps reading message.

code:

aurinko@pc:~$ lspci | grep vga 01:00.0 vga compatible controller: nvidia corporation gf114 [geforce gtx 560] (rev a1)

looking @ additional drivers program, first using nvidia accelerated graphics driver (version current) , changed nvidia accelerated graphics driver (post-release updates) (version current-updates) in hopes of helping, no. can't guess driver newer, because reason don't show version numbers there.

tried section "adding undetected resolutions" https://wiki.ubuntu.com/x/config/resolution.

code:

aurinko@pc:~$ cvt -v 1600 1200 85 # 1600x1200 84.95 hz (cvt 1.92m3) hsync: 107.21 khz; pclk: 235.00 mhz modeline "1600x1200_85.00"  235.00  1600 1728 1896 2192  1200 1203 1207 1262 -hsync +vsync aurinko@pc:~$ xrandr --newmode "1600x1200_85.00"  235.00  1600 1728 1896 2192  1200 1203 1207 1262 -hsync +vsync xrandr: failed size of gamma output default aurinko@pc:~$ xrandr --addmode default 1600x1200_85.00 xrandr: failed size of gamma output default

nothing happened after that, , page doesn't next, after searching internet more, tried typing this, didn't either:

code:

aurinko@pc:~$ xrandr --output default --mode 1600x1200_85.00 xrandr: failed size of gamma output default xrandr: configure crtc 0 failed

so section of wiki page doesn't help.

i've surfed net bit more, , 1 page said run nvidia-xconfig , fix everything. fine, tried:

code:

aurinko@pc:~$ sudo nvidia-xconfig [sudo] password aurinko:  using x configuration file: "/etc/x11/xorg.conf".  validation error: data incomplete in file /etc/x11/xorg.conf.                   device section "default device" must have driver line.  backed file '/etc/x11/xorg.conf' '/etc/x11/xorg.conf.backup' new x configuration file written '/etc/x11/xorg.conf'

but no, didn't fix everything. , page didn't explain next either. thought i'd try restarting computer, though wasn't mentioned anywhere.
bad idea. after stuck 640x480, , when tried run xrandr commands again, got (i wasn't able copy/paste screen being tiny , scrollbars , such missing, might not same):

code:

xrandr: screen cannot larger 640x480 (desired size 1600x1200)

so went , restored xorg.conf backup, because nothing seemed work right resolution, alt+tab didn't switch away terminal window @ all, asked me if wanted list 2217 possibilities (wtf??), pretty impossible use, because couldn't switch between windows google more.

pages should edit xorg.conf manually, have no idea put there, has 3 lines @ moment, , i'm guessing can't copy file old ubuntu box because box has different hardware.

have ideas on try next? feels frustrating changing resolution hard.

the way generate modeline have done using xrandr. run nvidia-settings , save xorg.conf file using highest resolution available in nvidia-settings. go xorg.conf file , manually replace generated nvidia-settings modeline 1 xrandr gave me. perhaps modeline old box work well.

it's idea read on how delete xorg.conf command line in case xorg.conf file doesn't work , dumped there.
