Hi there. I've always had that problem myself and before KDE 4.0 I had always been able to fix it thanks to gdm/kdm config file (depending on the one I had on my laptop).
Well this time it went all differently when installing Kubuntu Remix. Once installed, when the login screen appeared I switched to text mode (CTRL +ALT +, say, F5), and went looking for such a conf file as I was used to doing in older versions of (K)Ubuntu. I soon gave up. But just now I found the way to solve this in a forum. It not only solves the login screen High DPI fonts you are used to, but also the all-KDE4 dpi problem and all. I can't tell whether it is "correct" to solve this that way, but it works and seems to be a good work-around at least. Just go to your xorg.conf file in /etc/X11/ and change it, 1. At login screen, press CTRL+ALT+F5 (or another working one) 2. log in with your user account 3. then go to the proper directory using "cd /etc/X11" 4. then edit it as root using "sudo pico xorg.conf" 5. go down to the screen section and insert a line (which should be the last line between Section Screen and EndSection) 6. here is the line to add: Option "DDC" "no" 7. Leave using CTRL+X and pico asks you whether to save, answer yes, of course. 8. once back to the shell prompt, just reboot the computer using " sudo reboot " 9. Enjoy! I hope this helps. -- KDE 4 Migration - GUI is rendered huge https://bugs.launchpad.net/bugs/209053 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
