Description of problem: After upgrading to Fedora 20, letters on screen become giant. Display capplet shows screen as being 7", while this is in fact 42" Samsung TV connected to HDMI. Graphic chip is Intel. # cat ./devices/pci0000:00/0000:00:02.0/drm/card0/card0-HDMI-A-3/edid | edid-decode | grep size Maximum image size: 89 cm x 50 cm Version-Release number of selected component (if applicable): control-center-3.10.2-3.fc20.x86_64 kernel-3.12.5-302.fc20.x86_64 xorg-x11-drv-intel-2.21.15-5.fc20.x86_64 Additional info: This computer was first installed with F16, upgraded every half a year, and this is first time such problem appear.
Same issue here but then with the nouveau driver on Fedora 20. My 50'' Samsung TV is also connected using HDMI and is being reported by GNOME control center as a 'Samsung Electric Company 7''' screen and my fonts are way oversized. When I disconnect the TV and switch to my internal notebook display the font size becomes normal $ cat /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0/card0-HDMI-A-1/edid | edid-decode |
