I have an acer widescreen monitor set at 1024x768 running Ubuntu 12.04.4 precise, I have adjusted the resolution to match in display settings however the ubuntu side bar and files are all enlarged. its like it has zoomed in. I have read through all other related posts and cannot come up with a fix. The desktop was fine up until 3 days ago then it changed and I have no idea why, can someone help? Thanks
