widescreen resolution xubuntu 9.10

**Miscellaneous** · November 12th, 2009

Hi.

First of all, I know there are a lot of [resolved] threads related to that topic already. In my opinion: none of them work. I am going round in circles. Please help!

I am trying to plug my widescreen TV into my baby-dell (optiplex sx260). I can only display 4:3 ratios at the moment. The max refresh rate the TV supports seems to be 60Hz.

Obviously the GUI tool does not offer any widescreen 60Hz mode.

--------------------

Here is my system:
Linux hostname 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux

I have installed the Intel driver I found on some thread in this forum:
$ dpkg -l xserver-xorg-video-intel
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Description
+++-===============-===============-==============================================
ii xserver-xorg-vi 2:2.9.0-1ubuntu X.Org X server -- Intel i8xx, i9xx display dri

-----------------------

I have tried setting the driver to "Intel" and setting the resolution in xorg.conf, it seems to be completely ignored:

Section "Device"
Identifier "Configured Video Device"
Option "UseFBDev" "true"
Driver "intel"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Depth 1
Modes "1152x864"
EndSubSection
EndSection

---------------------

I tried installing 915resolution as specified on this forum as well: can't find the package.

----------------------

I also read this https://wiki.ubuntu.com/X/Config/Resolution
I tried xrandr: it does nothing at all. For example if I type xrandr and pick one of the possible resolutions (even 4:3 ratio), and then type:
$(sudo) xrandr --output LVDS --mode 1152x864 --rate 60
nothing happens.
I added a modeline anyway for the heck of it:
$ cvt 1152 864
# 1152x864 59.96 Hz (CVT 1.00M3) hsync: 53.78 kHz; pclk: 81.75 MHz
Modeline "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync
$ xrandr --newmode "1152x864_60.00" 81.75 1152 1216 1336 1520 864 867 871 897 -hsync +vsync
$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2048 x 2048
VGA1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm
1280x1024 60.0*+ 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
1152x864_60.00 (0xf9) 81.8MHz
h: width 1152 start 1216 end 1336 total 1520 skew 0 clock 53.8KHz
v: height 864 start 867 end 871 total 897 clock 60.0Hz
$ xrandr --output LVDS --mode 1152x864_60.00

Nothing happens. I guess it's normal since the X settings are just ignored. All I want to know is where the settings are... It's not using the xorg.conf file and there's no monitors.xml under .config either...

Well, at Ubuntu the settings come from the Videocard driver

Did you install that one?

$(sudo) xrandr --output LVDS --mode 1152x864 --rate 60
nothing happens.

The LVDS output is for your laptop panel. You probably want to use "VGA" to control an external screen. http://www.thinkwiki.org/wiki/Intel_...ay_with_XRandR

Hi! Thanks for helping!

Bunnybugs:
I'm sorry but could you please talk to me like an idiot, because well, I am one.
I thought that this Intel thing was already it... The xserver-xorg-video-intel package that I installed with apt-get. If I remember correctly I did that because Google told me those machines have an Intel video chipset or something along those lines.

So, what am I supposed to do to figure out what driver I need and how to install it?

Temüjin:
Aaaaaah that's what it is? I was wondering what those letters meant!
If I try with VGA, nothing happens, if I try with VGA1, it says "cannot find mode 1152x864_60.00" (this line is still in the list when I type xrandr though).
