I'm using Backtrack 5 R2 , what is based on Ubuntu 10.04 LTS.
It is installed on Samsung Laptop , and default screen resolution in Windows for it is 1366x768 , but BT/Ubuntu Screen Resolution GUI tool (System=Preferences=Monitors) shows that only resolution available is 1024x768 , and called my monitor as "Unknown".
Found a solution , that I have to change resolution in /usr/share/xresprobe/xorg.conf , but I did it , logged out/in and restarted many times , but it took me nowhere.
Tried with xrandr , but it shows only mentioned 1024x768 as only solution , and when I tried to input needed resolution , but it did not accept it , because it is not available.
As much as I googled , there are a lot of people that had similar problems with BT , but most of them solved with VirtualBox additional tools , but it can't help me , because I've installed it as second OS.
In one forum read , that same problems is in Ubuntu 12 , so I ask this question here.
