Getting the right mode for an LCD monitor (in GNU/Linux)
Friday, December 21st, 2007 by Favio
Usually, setting a new debian box with fluxbox as a desktop environment, is fast, easy, an uncomplicated (if you have done it 10 times already). What I didn’t know, was that using a widescreen LCD monitor would mess things with my usual setup.
The first problem you notice, is that the fonts look awful. At first, I thought it was something to do with anti-aliasing, but changing resolutions with xrandr showed me the real problem.
After looking for about 1.5 hours without success, I decided to let it go for the day. The next day, refreshed, I was able to assess the problem in a more calm way. This post was the starting point on the road to monitor resolution bliss. Only problem was that all the links mentioned were not working. Information doesn’t lie static for more than 1 year. So next step was to try pulling the results from google’s cache. And there it is.
