I want to increase the resolution of my Acer Aspire One D250-1326 which has Ubuntu 11.10 installed. The native resolution is 1024x600 and I want to increase it to 1440x810 or 135%. I've tried two methods that both use xrandr...creating a new resolution mode and applying it to my display, and scaling the display.
This picture shows the commands I entered into the terminal to create a new resolution mode:
Enter "xrandr -q" to show that the current resolution is 1024x600.
Enter "cvt 1440 810 60" to find the modeline for a resolution of 1440x810 at 60Hz.
Enter "xrandr --newmode..." to create the custom mode.
Enter "xrandr --addmode LVDS1..." to apply the mode to my netbook display. Here is where I experience the "BadMatch" error. Note: When I enter "xrandr --addmode VGA1..." instead, the mode is successfully applied to the VGA1 display.
The second method I attempted is scaling the display. I had success using this method when I used Ubuntu 11.04. Now for some reason, when I use the same scaling command, my mouse becomes constrained to the top-left portion of the screen. Here are the steps I took:
Enter "xrandr -q" to show the current state of the display. Note: You can see the mode I created during the previous method. Again, I was not able to apply it to the LVDS1 display, but I could apply it to VGA1.
Enter "xrandr --output LVDS1 --scale 1.35x1.35" to scale the display. After this is done, the resolution is changed but the mouse cannot move any lower than you see here in the picture.
I also tried using different panning options without any success. One route I did see is to revert a patch which is said to solve the scaling problem. I have not been able to figure out how to perform this action though. Here is a link, with the confirmation near the bottom: BUGS(dot)freedesktop.org/show_bug.cgi?id=39949 (Dang spam prevention, can't post >2 links)
I would appreciate your help solving this problem. Otherwise I guess I'll just go back to 11.04. Thanks
