The problem is this line in /var/log/Xorg.0.log: (II) NV(0): Setting screen physical size to 508 x 317
I have measured the screen and it is actually (approximately) 368 × 230. This error causes fonts to be shown in the wrong size (too small). I think that the fonts became smaller after some upgrade during the last few months. I do not know if it was correct before that or if it was just wrong in a different way. I tried to tell it the correct values in /etc/X11/xorg.conf: Section "Monitor" Identifier "Monitor" DisplaySize 368 230 EndSection Section "Screen" Identifier "Screen" Monitor "Monitor" EndSection It is read without problems: (==) Using config file: "/etc/X11/xorg.conf" (==) No Layout section. Using the first Screen section. (**) |-->Screen "Screen" (0) (**) | |-->Monitor "Monitor" But then it sets the wrong physical size anyway! Is there anything to do besides reporting a bug and waiting? (There are other issues with this video device; it shows only 25 × 80 characters in the virtual terminals (should be 75 × 240). This is the new Dell vostro|1720 from November, that replaced the old INSPIRON|8600 aquired 5 years earlier, with radeon driver. That old device worked fine without any configuration files. The physical screen size was detected and the virtual kernel output switched to 75 × 240 characters as soon as the device was detected.)
