After my laptop's screen broke down, I sent the laptop back to have the screen replaced. Unfortunately, it seems that they replaced it with a lower resolution screen.
I have the faint hope that the screen's resolution is actually higher that what Ubuntu is able to display (although it seems unlikely).
Is there a way to know for sure the physical (or "theoretical") resolution of the screen?
Edit: I tried xrandr as suggested in the comments, here is the output:
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 32767 x 32767
LVDS1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
1366x768 60.0*+
1360x768 59.8 60.0
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
Does this mean there's definitely no way the screen could be actually higher res than 1366 x 768? (I was expecting 1600*900)
Edit: Not sure why my question was downvoted. Anyway, since it seems there is no easy way to know for sure the native resolution of the screen, I fetched a screwdriver, took the screen apart to get its reference, and looked it up. It was a 1366x768 indeed, as I feared.
xrandr
is the tool for that :) Here: askubuntu.com/questions/186288/…
