방금 Virtualbox를 이용해서 우분투 12.04를 설치했는데, 풀스크린모드만 켜면 계속해서 마우스나 키보드가 입력되지 않고 매우 버벅이는 문제가 있는 것을 발견했다.

이에 대해서 열심히 이리저리 찾아다니다 보니 16:9 해상도에 대해서 이런 문제가 발생하는 듯 했다. 결국 사람들은 1600x900이면 1599x900등으로 사용하는 방법으로 해결하고 있던 듯 하여 나도 그런 방법을 시도하려는 찰나 완벽한 해결법을 발견하여 정리해둔다.

귀찮으니 복붙만..

I tried the work around to set the modes the width to 1 pixel less than the actual width. And it worked for me in fullscreen. However after exiting from full screen the resolution remained at that value. (it did not auto adjust)

Anyway after rummaging through more links online i found out that there are certain workarounds in the compiz settings manager. i was able to find one particular option that solves this problem (Yippie!!)

first you need to install compizconfig-settings-manager using sudo apt-get install compizconfig-settings-manager.

Then in Preferences->Compizconfig-settings-manager look for Utility. And then ‘check’ the workaround item. Finally in the settings for the workaround item, look for 'Force fullscreen redraws (buffer swap) on repaint’ and check this option. Thats it!

It worked for me. I had been looking for a fix for several weeks.:D
