I have reviewed the answers that exist. I trialed Ubuntu 14.04 on my Novatech U50SI1 and it ran perfectly albeit slowly, so I installed it in place of Windows XP.

When I booted up 14.04 my screen resolution locked at 800x600 and I do not have the option in settings to have anything other than this resolution.

The text is therefore very large and the screen overflows so that I cannot scroll to some of the command buttons.

Xrandr just errors out with "invalid resolution", no matter what I type (even 800x600).

When I boot from the disk the screen resolution is fine. I think the video card for this model is SIS Mirage 3 but I am not sure how to check. The only driver updates I have found are for windows not Ubuntu and they all have .exe files my Ubuntu install will not run.

I hope this is now clear. My question is how do I change the resolution and also run .exe programs?

    what video card are you using and what error is xrandr giving you? – Panther Nov 01 '14 at 20:37
  • That's two unrelated questions. The second is answered here: http://askubuntu.com/questions/988/how-can-i-install-windows-software-or-games – muru Nov 03 '14 at 22:26
  • To show what graphics card you are using, open the terminal and run the command: lspci -nn | grep VGA. The output of this command will provide sufficient information to determine what graphics driver(s) are compatible with your system, so please edit your question and add the output of lspci -nn | grep VGA to it, or else post the output as a comment. – karel Nov 04 '14 at 01:10

I would suggest going to System Settings/Software & Updates/Additional Drivers/Selecting a driver for your video card, assuming this was not done already. I had the same problem after installing Ubuntu and that is how i solved it.

  • That is a good idea .. the only problem is that it is an older PC that I inherited and I have no idea what the video card is, nor how to find out. I suppose that I could try to contact the supplier – Chris Croxson Nov 02 '14 at 09:10
  • Assuming you're using Ubuntu 14.04 as mentioned in the original post; the menu i mentioned lists the detected video adapters and lets you select from provided drivers.

    Also the top right menu/About my computer should tell you something about the graphic adapter.

  • Try getting the card information from the system using lspci or lshw -C display – Underverse Apr 11 '19 at 23:05
