adding undetected screen resolution with xrandr in lubuntu
- date: May 22, 2012
I am having some troubles changing the screen resolution in lubuntu.
It is an old destop pc, with a nvidia 5900 gfx, and as far as I know that is not supported in the newest nvidia drivers for ubuntu 12.04 (something to do with X, I believe) so I am using the nouveau driver that lubuntu came with.
My current resolution is 1024*768 which screws up the aspect ratio on my 16*9 full HD monitor.
Therefor I would very much like to change the resolution to 1366*768.
Here is the output from xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
800x600 60.3 56.2
DVI-I-1 disconnected (normal left inverted right x axis y axis)
TV-1 disconnected (normal left inverted right x axis y axis)
it says that max resolution is 4096*4096 so I'm assuming it sh
14.04 Trouble Adding Resolution with xrandr; errors
- date: July 11, 2014
TIA for your time and effort with my issue. I'll do my best to be specific while being brief.
Lenovo T530 with an NVIDIA GF108M [NVS 5400M] rev. a1
Ubuntu 14.04 LTS, Unity, Fully Updated.
I need to add a different resolution than is set-up. xrandr does not display the resolution as available.
I found the solution to my problem thanks to this thread.
My Issue begins during the xrandr --addmode step.
I'll post my commands and the results so you can follow along and find where I shot myself in the foot.

trying to write a script for screen rotation with xrandr...
location: ubuntuforums.com - date: January 25, 2011
So, I want to write a script that toggles my screen rotation between normal and left, but I don't know what I'm doing. I wrote this:
#screen rotation script that toggels between left and normal
if [ $Orientation="normal" ]; then
xrandr -o 1;
xrandr -o 0;
Right now, it just changes the screen orientation to left no matter what.
I really have no idea what I'm doing. Be gentle.
Screen Resolution. with SiS graphics. Cant get xorg.conf to help...
location: linuxquestions.com - date: March 4, 2009
I'm attempting to put Ubuntu 8.10 onto a HP T5720 thin client (don't ask why, its just me being geeky). but I'm having a few problems with getting a high screen resolution (eg. 1280x1024) > (which is a problem I seem to forever have with ALL Linux distros (on many different computers) and it keeps putting me off from using it instead of Windows...) - there must be a simple solution???
I've looked up some other posts/forums about getting it to work, but I'm still stuck - so hopefully someone can help me out?!
OK. my lspci | grep VGA shows:
how to define screen resolution with virtual desktop
location: ubuntuforums.com - date: February 3, 2012
Im running lubuntu in a virtual box environment. The problem I have is that the maximum screen resolution is 800x600 and I cant find out why.
I have set the video memory to 128MB and enables the 3D acceleration from within the virtual box manager but this has made no difference.
I did some google searches and found out that the resolution is controlled by xrandr (perhaps thats not technically correct - but it is how i understand it).
I tried to run xrandr -s 1240x1080 and other resolutions but this did nothing.
I then ran xrandr -q and it said that the maximum resolution was 800x600.
I am stuck as to where to got next. Could somebody please suggest something? I am new to linux but am reasonably comfortable with the console and would like to get my hands dirty
Configure 1600x800 screen resolution with radeon 5000 series (hd 5730)
location: linuxquestions.com - date: February 17, 2010
I know this is an issue that a few people have asked about, but spending the past few hours searching and messing around hasn't been productive.
I have a new system with an ati mobility radeon hd 5730 chip. As far as I know, there are new drivers in the works, but aside from some articles, I haven't found anything that specifically tells me how to get them installed/working (at least, so that it works for the 5000 series of radeon chips).
Has anyone had any luck with this yet? I'm just at the stage of installing, so I don't really care if it involves a different distro, etc. I've tried Ubuntu 9.10 and 10.04-alpha2, as well as Fedora 12 (from the live CD) and so far no luck.
At the moment, all I care about is getting the native 1600x800 working for my screen. I haven't a clue how do do that...it seems like I might be able to do this using xrandr, but I don't know how to create a mode properly.
Any suggestions would be greatly appreciated...
Screen Resolution with Xorg.conf
location: ubuntuforums.com - date: July 14, 2013
Hi everyone, I'm trying to change the default screen resolution for my monitor. I'm using a Radeon 5450 GPU but I'm using the open source drivers after no luck with installing the proprietary ones.
I'm trying to change the resolution with Xorg.conf, but the screen resolution won't change from 1024x768.
^That's the Xorg.conf, however I've changed the card for Card1 after seeing that needed to be changed.
Any help would be apprieciated.

adding 1366x768 screen resolution to amd machine
location: ubuntuforums.com - date: August 1, 2012
Hello. I just installed Ubuntu 12.04 onto a Gateway Lt3108h net book with an ATI/Radeon chipset. I have installed FGLRX so that the screen is stable but I need to add a resolution of 1366x768. I have been searching for the correct set of commands to do this in Terminal but I'm not having any luck. I am a very basic user so something simple would help immensely. Any help would be appreciated here.

Forcing a resolution with xrandr / lightdm (14.04)
location: ubuntuforums.com - date: April 1, 2014
I'm trying to set a specific resolution (1920x1200) so the resolution is persistent and applied for the login screen / greeter. In searching the forums, it seems that I should be making updates to lightdm.conf. However, it looks like the lightdm configuration files moved recently in 14.04. They used to be here: /etc/lightdm/ and are now here: /usr/share/lightdm/lightdm.conf
