Description Acsinte Florin 2014-04-06 11:34:57 UTC
There is no way to change the display size. 
Problem is that some displays are not correctly detected (dunno if it's a gnome thing, a driver thing, or maybe the display just says that it's 7 inches when it's not), and I cannot find a way to change that.

I an not saying about auto-detection (i know there are a lot of factors that can not be controlled), but a way to change the size is needed, especially since scaling does not scale very well (atm i have scaling set to 0.5, but this makes icons from dash too small, does not change the spacing between icons, and some cursor images do not scale at all (like when holding the cursor over a link, or over the address bar from the browser)).

> Problem is that some displays are not correctly detected

I guess that is the problem to solve instead. :)  Did you file a bug report against your distribution to track down the underlying problem?
Comment 2 Acsinte Florin 2014-04-06 14:31:33 UTC
i did not, but im guessing arch uses the vanilla version, so..

Still, even if auto-detect worked, id still say that missing the ability to modify the screen size is a pretty important bug.. The monitor might not say it's size (because it's old, or because it's a cheap TV used as a monitor, and it does not provide that information), or the user might just want to modify it, for his own personal reasons..

We're not really interested in adding support for custom modelines and resolutions. What's the output of "xrandr -q" on that machine? If supported resolutions are missing from the output, you'll need to file a bug and follow up with your X.org provider (eg. your distribution, or the upstream X.org) rather than with us.

Reopen this bug if "xrandr -q" shows the resolution you wanted to use, but GNOME doesn't.
Comment 4 Acsinte Florin 2014-04-07 11:03:51 UTC
The resolution works fine, the size of the display however is wrong.

The display is 1366x768, 22 inches. 
Gnome says it's 1366x768, but 7 inches, so everything is a lot bigger (looks like a tablet).

The wrong size is reported by the display itself, nothing we can do there.

The "everything is a lot bigger" problem has already been fixed in the GNOME 3.10 branch of gnome-settings-daemon. See bug 709859.

I know there is nothing to do on the auto-detection side, i was saying about being able to change it for this case.. I am using 3.10 and i still have this problem.

There are work-arounds in the other bug. You can also use X.org directly to override the detected screen sizes, but it's not something that we'll do directly in GNOME.

Ask your distribution to ship the patches, or wait for the next 3.10 point release.
