How do I fix the HDMI/DVI display output with Intel HD 4000 Graphics in 12.04?
I downgraded the kernel to Lucid (10.02) kernel. (2.6.32) while running Precise (12.04). That fixed the problem of DVI/HDMI. Very likely, the problem is in one of intel related kernel modules.
I also tried xorg Lucid, which did not fix, and the tip or xorg, and did not fix. So, it's kernel module related for sure.
You can add the Lucid to apt's source and downgrade the kernel to Lucid's 2.16 kernel. That should get you going.

I have an Alienware Dell PC with Intel HD 4000 Graphics (Ivy Bridge) as verified by the output of
lspci | grep VGAposted below.
00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09)
The PC only has HDMI and DVI display outputs and using the HDMI output I am only being offered abnormal resolutions. As you can see below it does not even list HDMI1 or DVI1 but just only a fallback.
$ export DISPLAY=:0.0 && xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1360 x 768, maximum 1360 x 768 default connected 1360x768+0+0 0mm x 0mm 1360x768 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0
How can I fix this? Does it just need to be configured differently or will I need to use a newer kernel (as Intel Graphics drivers are included in the kernel)?
Follow up: kernel to latest
Go to: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Go to last: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/ Download: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-headers-3.6.0-030600rc3-generic_3.6.0-030600rc3.201208221735_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-headers-3.6.0-030600rc3_3.6.0-030600rc3.201208221735_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-image-3.6.0-030600rc3-generic_3.6.0-030600rc3.201208221735_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-image-extra-3.6.0-030600rc3-generic_3.6.0-030600rc3.201208221735_amd64.deb
sudo dpkg -i linux*.deb
Step 3: reboot which shows that i have Ubuntu 12.04 with latest
$ uname -a Linux sun-Alienware-X51 3.6.0-030600rc3-generic #201208221735 SMP Wed Aug 22 21:36:32 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
But still same problem remain.
adempewolff almost 10 yearsWhat kind of graphics card do you have (HMDI and DVI are usually routed through the graphics chipset)?
adempewolff almost 10 yearsAlso please add exactly what problems you are having with the HDMI/DVI output(s). Are they not working at all, working partially, being buggy, or what? The more specific you are the more likely you will get a helpful answer.
adempewolff almost 10 yearsand what's your graphics card?
lspci | grep VGAshould do the trick if you don't know.

Admin almost 10 years@adempewolff: i think its solved: gist.github.com/3424755
Admin almost 10 years@adempewolff: only problem is its not 1024x768. I need to have 1280x720 resolution with xorg.conf file. Do you know how? Then it answers the whole mistery.
adempewolff almost 10 yearsUbuntu doesn't have an xorg.conf file by default. you can create one with
sudo xorg --configureand then move it to the correct directory
sudo mv xorg.conf /usr/share/X11/xorg.conf.d/
Admin about 8 yearsSame here, after the update it wasn't working. I downgrade to 3.13.0-27 and is working. Something wrong with the kernel module.
