    Changing xorg screen resolution

    Hi, since upgrading to f30, the screen resolution changed to 320x400 and there are all sorts of crashes including "Settings failed" and segfaults of gnome-control

    Code:
    264.126456] gnome-control-c[10094]: segfault at 0 ip 00005565645e41d4 sp 00007ffc577ed348 error 4 in gnome-control-center[556564598000+126000]
    [  264.126464] Code: 00 00 00 0f 1f 00 f3 0f 1e fa 48 8b 07 ff a0 a0 00 00 00 0f 1f 00 f3 0f 1e fa 48 8b 07 ff a0 a8 00 00 00 0f 1f 00 f3 0f 1e fa <48> 8b 07 ff a0 b0 00 00 00 0f 1f 00 f3 0f 1e fa 48 8b 05 65 d9 3c
    I have a Radeon HD 7450 controller:

    Code:
    03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos PRO [Radeon HD 7450]
    How do I determine which driver is being used and how to ensure it's using the correct one?
