Description of problem: My Acer AL2216W LCD monitor worked correctly in 2.6.23.15-80.fc7-i686, no longer does in 2.6.23.8-34. Screen Resolution Preference setting 1680x1050 @ 60Hz produces a vertically squashed image padded with black top & bottom -- the video scan does not occupy the entire screen; Window system text displays badly. Google search produces: "...Custom Timing Advanced dialog ... set the Timing standard to 'CVT reduced blank'..." is required for 1680x1050 @ 60Hz to display correctly on this monitor. This monitor worked correctly under 2.6.23.8-34.fc7-i686 Version-Release number of selected component (if applicable): 2.6.23.15-80.fc7-i686 How reproducible: Upgrade from 2.6.23.8-34.fc7-i686 to 2.6.23.15-80.fc7-i686 and restart. Steps to Reproduce: 1. 2. 3. Actual results: Monitor/Graphics card display a vertically squashed image padded with black top & bottom -- the video scan does not occupy the entire screen; Window system text displays badly. Expected results: This monitor worked correctly under 2.6.23.8-34.fc7-i686 Additional info:
That's.. odd. Booting back into the old kernel definitely makes it work again ? Can you attach the /var/log/Xorg.0.log from both working/fail setups? Thanks.
Also please attach the contents of /proc/iomem from both kernels.
