I can confirm that setting about:config -> 'layou.css.dpi' to 96 solved my font-rendering problems in FF (and persist in all other Gecko- rendering applications I have installed).
xdpyinfo gives me: screen #0: dimensions: 1680x1050 pixels (300x230 millimeters) resolution: 142x116 dots per inch For the sake of completeness, I assume https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/201032 is the root cause. Or? (And thanks for the workaround, Alexander -- hero of the day!) ** Changed in: firefox-3.0 (Ubuntu) Status: New => Confirmed -- Firefox uses the wrong DPI https://bugs.launchpad.net/bugs/201487 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
