Yes, something is wrong. This window is supposed to host at least two tabs, and resolution settings are on another tab. This will show you what KCM modules are present. kcmshell4 hardware --list The one called kcm_kscreen must be present. May be although reinstall kscreen package sudo apt-get install --reinstall kscreen

I dont know if this solution will work for everyone, but it seemed to work for me. Basically I ran a bunch of videos on VLC and the nytimes for a while until my computer fan turned on high, then reboot. The problem fixed itself. Maybe running a lot of videos does something to remind the computer what the right size is? I don't know, anyway, if I check ...

Go to the top left (in unity) and search for 'additional drivers'. Install the recommended or proprietary drivers. You might have to reboot. If this doesn't work, add a comment on this answer and I'll try again.

Kinda stupid that I can't just comment, but whatever. It might be an overscan problem. There should be a 'just scan' option on your TV. If not, it might be an overscanning problem with Ubuntu, which can be set in xorg config settings. Does your mouse 'hit' the top of the screen? Or does it go past the top?

Solved by downloading new nVidia drivers.

I have found the problem, for anyone that's stucked like I was for now, and have the same output for xrandr, here's the solution: xrandr --newmode $(cvt 1280 1024 60 | grep Mode | sed -e 's/.*"/1280x1024/') xrandr --addmode DVI-1 1280x1024 After that you can change the resolution by going to display

Does the Display / Screen / Monitors settings page (whatever it's called in your DE) have any options to change resolution, & do they work? And according to xrandr there you should have 4 resolutions available, have you tried changing it with xrandr, maybe with xrandr -s 800x600 or whichever you want, with/without -r 60? For a different mode, not ...

I have found the solution to this problem and will proceed with how I came to solve the issue. The problem was not caused by the Nvidia driver or GTK like I originally thought but was due to an old bug in Compiz to do with the screen refresh rate on Nvidia cards as pointed out by Mateusz Stachowski on Google+ who also provided a link to the bug report on ...

Install arandr sudo apt-get install arandr 2. Run xrandr If your chosen resolution exists (regardless of which monitor it appears by) then skip the next step If your resolution does not exist, create it by doing the following: In this example the resolution I want is 1280x1024 cvt 1280 1024 This will create a modeline like this: "1280x1024_60.00" ...

Your installation may hae simply diabled your ability to bot to Windows. Insert any windows recovery disk or Windows installation disk you have lying around and let it repair it's boot. After you regain access to your windows, do the Ubuntu installation again overwriting your existing installation (It may be corrupt).

There are workarounds: you can, for example, adjust dpi for the most dense screen, and use xrandr to downscale other screens (to keep it crisp). See my answer for a relative question: Is it possible to have two different DPI configurations for two different screens? PS: sorry, the topic is a duplicate, but I do not know how mark it as duplicate - so just ...

It seems people are still struggling trying to work with several monitors and HiDPI displays. A good workaround is described in arch wiki https://wiki.archlinux.org/index.php/HiDPI#External_displays . So, I have: laptop asus ln303ux: 3200x1800, external monitor: 1920x1200 Now I use Ubuntu 14.10 & GNOME Shell 3.12.2 that has pretty usable HiDPI ...

In my case, adding this line to "Device" Section of the xorg.conf file solved the problem. Option "ModeValidation" "NoMaxPClkCheck" As seen in this Question.
