Xandr -output HDMI-0 -mode 1920x1200 and all works as expected. Restart lightdm and Im good to login in 1920x1080, after that I could use Poor graphics mode, than I run modprobe radeon setmode=1 from a text console Out that if I boot the kernel with appending the nomodeset option it boots into I booted the new kernel into recovery mode and after a few tries I managed to figure f6 to check text consoles all of them were pitch black. After doing so and purging fglrx as described on the help wiki of ubuntu I decided to go back to the OSS drivers and recompile a new version of the kernel 3.10.9. I could get 1920x1080 workingīy tweaking the scaling bar Underscan/Overscan option but the text was blurry I was not happy with it, I wanted the native resolution.

Was set 'use graphics process for scaling', I could not select 1920x1200 only 1920x1080, when it was selected to scale with 'use display for scaling' I could select 1920x1200 but I had the same black border covering up desktop space and windows overlapping the visible are when maximized. To install the proprietary fglrx Catalyst drivers.Īfter installing fglrx I tried the scaling options from the control panel. I triedĪ number of things, I can not recall them exactly but eventually I gave up and tried The only other option I could achieve with some tweaking was to have a black border around the screen either covering up the desktop or with a downscaled version of the desktop.Įither way it was not working properly. The Ubuntu caption at the login screen was cut off. Here are some visual mockup approximation of what I could achive. Of the window would be off the screen on the top and the two sides.

So if you put a window in full screen the edges In the native resolution of the screen which is 1920x1200 the desktop would overlap Something going wrong with the EDID of the screen not sure, see the bottom for some Properly - maybe it is something else than upgrades not sure. I am not sure what happen, but after a few apt-get upgrades it stopped working Through HDMI, but the results were the same through the DVI interface as well. The card is an ATI Radeon 5770 connected to a ViewSonic VX2835wm 28” screen Which I compiled and it was working very well. I had the OSS Radeon drivers configured with 3.9.0-030900-generic kernel So seems like 3.10.9 is my best bet if I can live without the audio through hdmi Question is still, how to get the native resolution of the screen workingĪlso tried 3.11-rc7 kernel, the overscanning / underscanning issueĪdditionally there is no HDMI audio device - same kernel config It all as some parts of it goes "under" the black borderģ.10.9 kernel does not have this underscan issue, but no HDMI audio, otherwise the video output is just black screen This way the desktop probably fills up the physical display, but I can not see Underscan-on xrandr -output HDMI-0 -set underscan off -mode 1920x1200 This way I can see my entire desktop, but there is a roughly 100 pixel black border So getting closer but still not perfect, with 3.9.0-030900-generic kernel xrandr -output HDMI-0 -set underscan on -mode 1920x1200 Turns out this is called overscan / underscan problem.
