Thinkpad W520 TwinView under Linux Debian Wheezy (Mint LMDE)
Posted: Fri Aug 24, 2012 5:18 am
Hi all,
I've run into problems when trying to setup a dual monitor display on my ThinkPad W520. Until now I was running on nouveau drivers (graphics are set to discrete under BIOS). The only significant problem I had was that from time to time when I've tried plugging external monitor through DisplayPort, the system freezed until I pulled the cable - then it came back to normal in a moment. For that reason, I've tried switching to binary drivers - that change in turn forced me to create an xorg.conf in order to explicitly configure display and input devices. From now on, I can't make the external monitor work. And even if I do, it stubbornly switches to ultra low resolution (like 640x480). I've tried various metamodes, explicitly declared monitor's horiz/vert sync - to no avail.
For reference - my external display is Samsung SyncMaster 214T and I'm plugging it in through DP <-> DVI adapter.
My current xorg.conf is pasted below:
Any help and or feedback on alternative methods to achieve what I want are welcome. Thanks in advance.
