Im using a laptop with intel graphics and I would like to know how to change the screen resolution. Ive tried following a guide on the wiki and it asks to use a tool called xrandr to identify my monitor name and device name, and im not sure how to do that. Any help would be appreciated thanks 最后进行编辑的是 skaveria on Mon Mar 12, 2012 3:54 pm, 总计第 1 次编辑

Mine was: 代码:  # 1368x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 85.86 MHz   Modeline "1368x768_60.00"  85.86  1368 1440 1584 1800  768 769 772 795  -HSync +Vsync 2. Define new mode. My example: 代码: xrandr --newmode "1368x768_60.00"  85.86  1368 1440 1584 1800  768 769 772 795  -HSync +Vsync Of course, you'll got different numbers there. 3. Add new mode: 代码: xrandr --addmode default 1368x768_60.00 4. And the last step: 代码: xrandr --output default --mode 1368x768_60.00

My Monitor supports the resolution, it was working before I bought the PCIe card, back then I used the built in card (Radeon HD 3300). Thank you. _________________ Cowabunga!
