I am using fedora workstation 21 KDE 64bit. I have "amd radeon hd 5450" which have 1gb memory. i installed amd graphic driver using this tutorial Everything worked fine and I rebooted. After reboot loading screen of fedora changed but after that I see "input not supported" box floating around. I know it means that the monitor does not support this input but how to change that input. i can access tty2 and others. my monitor supports resolution of 1400x1050_60.00 please help me.

Well, I thought I previously posted a comment here, but it appears to have disappeared. I've never seen that particular issue before (that's my tutorial to which you link), but it may be that the strange resolution of your monitor is to blame - try executing aticonfig --initial --resolution=1400x1050, reboot, and see if that fixes it.

I have already tried it there is one problem --initial works fine but --resolution gives error.

Error: Section # expected
aticonfig: parsing the command-line failed

I think its missing something. There is Screen# in --resolution in aticonfig --help I dont know what it is.

Yeah, you're right - sorry about that; I thought I saw an example where the screen value was omitted. Try `aticonfig --initial --resolution=0,1400x1050
