Intel graphics card HD 4600 not supported in Mint 17

[marlar]

I have just installed Mint 17 on my new PC with a Intel HD 4600 graphics.

Unfortunately it does not recognize my monitor, a Samsung S27A850T 27" monitor cabable of running 2560x1440. The Display utility reports a 24" monitor with a maximum resolution of 1920x1200 which does not look nice!

I have tried googling different solutions for more than 2 hours without finding a remedy. Then I got the idea to boot up a Mint 16 a live image from USB and that works perfectly. It starts up in 2560x1440 without any fuzz.

This puzzles me. Why does Mint 16 use the proper resolution and Mint 17 does not? What can I do?

Thanks in advance,
Martin

No one?

You might want to compare results from

Code: Select all

xrandr

in terminal in LM17 and the Live LM16 to see what differences there are. A search for xrandr or xorg might help you find a way to correct it as you may just need to add a new mode in LM17 using xrandr

I have already followed the xrandr path, but when I try to change the mode, I get:
