Ubuntu has wrong resolution and won't let me change it

Question

Ubuntu 15.04 x64 gives me 800x600 when my screen can output 1600x900. I went into my display settings and there was only one option. Anything I can do to fix it? lspci -k | grep -EA2 'VGA|3D' Outputs

VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kabini

[Radeon HD 8240 / R3 Series] Subsystem: Acer Incorporated [ALI] Device 083a Kernal driver in use: fglrx_pci

Sorry for formatting issues

@kashminder It was working fine yesterday then I booted it this morning and it was that resolution. I went into additional drivers and it had automatically set to manually installed driver and it would not let me change anything. — Matt, Sep 26 '15 at 11:02
Please [edit] your question and add output of lspci -k | grep -EA2 'VGA|3D' terminal command. And specify the Ubuntu version. — Pilot6, Sep 26 '15 at 13:28

Run

sudo apt-get install mesa-utils

in terminal.This should hep you to change to correct resolution. In case your drivers are not upto date , try installing proprietary drivers from the Software and Updates section of ubuntu.

mesa-utils have nothing to do with resolution. – Pilot6 Sep 26 '15 at 13:29
I had similar problem. Installing mesa-utils solved it. – Aniruddha Sep 26 '15 at 13:30
@Pilot6 why are you so sure? – Alex Jones Sep 26 '15 at 13:39
@edwardtorvalds I seem to know what exactly mesa-utils installs ;-) It can't improve anything. You can look yourself. – Pilot6 Sep 26 '15 at 13:40
@Pilot6 it helped other person ;-) – Alex Jones Sep 26 '15 at 13:44
Take a look http://askubuntu.com/questions/190488/i-cant-change-my-screen-resolution – Aniruddha Sep 26 '15 at 13:45
There is no evidence that it helped anyone in the other question. And it is impossible anyway. – Pilot6 Sep 26 '15 at 13:56
