UBUNTU won't change display resolution to 2560x1440 on an iMac 27"
location: ubuntuforums.com - date: March 28, 2010
I recently purchased an iMac 27" i7 with 8GB RAM, however after i installed UBUNTU i can't seen to find a way to set my display resolution to 2560 x 1440.
Any help will be greatly appreciated.
This is my second try on UBUNTU, the first time i was happy but disappointed on how difficult changing settings could be, this time seems not to be any different.
Ubuntu 12.04 64bit on 2011 iMac 27" screen brightness
location: ubuntuforums.com - date: June 11, 2012
after being away from Ubuntu for some years, I decided to give it a try on my new iMac.
Dualboot, rEFIt... it all works, and appears to be stable. I managed to get the sound working, but there is one thing that bugs me: I canot adjust the screen brightness!
Not only is the screen too bright for comfortable viewing, it also makes the system run too hot! Not so hot that the fans kick in, but far hotter than when I use OSX. And we all know that heat is not beneficial for electronic components.
I searched an tried out various solutions I found on the Internet, to no avail. So I am turning to you people here:
- Anyone ith the same configuration as I have found a solution that works?
It would be sad if I could not use Ubuntu because of this issue, because, I have to admit, Ubuntu 12.04 with the Unity interface compares favourably to OSX when it comes to the the Žlook and feel' of it. I need to run Adobe Lightroom and Photoshop, so I will keep OSX, but I do not use these
How to change display resolution
location: linuxquestions.com - date: February 22, 2008
I am new here and new to Linux. I have an old Dell Inspiron 3000 that I have successfully installed DSL to, but I am having problems making the display correct. Everything on the desktop looks fine except that the bottom and the right side of the desktop is off the screen, so I need to either resize the desktop to fit the display or change the resolution maybe?
I have not been successful with either.
I am not sure what information is needed to diagnos the issue, but let me give at least this much. I am using GRUB as my loader and the command line I am using to boot with is as follows
CANNOT change display resolution in Fedora
location: linuxquestions.com - date: May 14, 2005
Just last night I installed the Fedora Core 3 release on my machine. Surprisingly the new nvidia driver installed fine.
Now I am using a Geforce 6800 Ultra AGP card, so I am weary about its support in Linux as it is. Whenever I got to System Setting > Display I click it, yet nothing comes up. Everything else works fine.
The reason I want to change the resolution is that I am using a widescreen and want a 1280X768 resolution. I already edited the xorg.conf file and still I can't even get to the settings screen to enable this resolution.
Is there another way to actually "ENABLE" and use another resolution? Also, I tried Preferences > Screen Resolution and 1280x768 doesn't appear.
Thanks for any help.
Need to change display for console on Ubuntu 12.04 server
location: ubuntuforums.com - date: October 27, 2012
I don't know if anyone here has encountered this or not, but here goes...
I just replaced a couple of Windows servers running SQL Server with Ubuntu 12.04 and PostgreSQL. The install is fine, but the console won't work with our Raritan Dominion KXII KVM (KMM, whichever you prefer). The KVM can't handle the resolution of the Ubuntu console. Apparently, the console runs at 1280x1024. I need it to run at a display just like RedHat/Fedora/CentOS use, 720x400, and may even need to change the font to get it to work. Basically, the RedHat-based systems use the old 80x25 (80x24?) character display and it works with the KVM. The higher resolution on the Ubuntu server creates a display that has a wider and higher character count (not sure what it is though).
Does anyone know how to change this? I can't do jack with the servers until this is fixed.
Thank you all,

Display resolution wrong on Dell Lat D410 (Ubuntu 13.04) with SVideo
location: linuxquestions.com - date: May 19, 2013
I am using a Dell Latitude D410 with Ubuntu 13.04. I'm trying to connect it to a Sony Wega widescreen TV (using a S-Video cable) to watch YouTube but the display resolution is set wrong. It should be 1280x720, but instead, Ubuntu is setting it to 1024x768. I know some shell skills, but I am a newbie to display administration. Please help.

So I've been building a Ubuntu install from the base system so that I'm specifically only running exactly what I need, so far, i've been doing it all over SSH as the screen won't work. I'm to understand I need to edit the xorg.conf file to the following 'geekery'
