View Full Version : [ubuntu] desktop appears smaller than screen

The very short story: I have a 17'' inch screen, but Ubuntu is not showing the desktop right: the screen appears to be shrunk, and I see two black vertical stripes at both edges of the desktop.

The longer story: I have a new Toshiba L355-S7915. When I tried Ubuntu 9.04 in the live cd, the screen appears as it is described above (shrunk with two black stripes left and right). However, when I made a proper install (a fresh install of ubuntu 9.04), and I logged in, the desktop fit the screen properly.

I have turned the computer on and off a couple of times, and sometimes, the screen showed properly, and sometimes it did not (in the later cases, I simply rebooted, and the screen was fine again). However, after I updated the packages that were installed by default the screen has been permanently screwed. (by the way, this new behavior seems to demand a lot of resources from my laptop... at least, with these new screen configuration, the vent is always on).

Any ideas as to what is the sort of thing that has to be fixed? (as I said, in the outset, the screen was fine).

Santiago.

In case this helps:


This is what I get in what seem to me to be relevant entries of lspci:


00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
Subsystem: Toshiba America Info Systems Device ff67
Flags: bus master, fast devsel, latency 0, IRQ 2299

This is my xorg.conf

And this is what I get in xrandr -q:

Go to System>Preferences>Display. Make sure Mirror Screens is unchecked, put the resolution as high as the resolution settings allows, set Rotation to Normal and click Apply. Log out and log back into your laptop user account.

Thanks a lot for your response. It seems that you are right (although, see below, I have not actually tried it yet).

As I said in the post that opened this thread, sometimes, when I turned off the computer, it automatically restarted with the right sort of screen. Well... this just happened.

None of the three items listed above (lspci, xorg.conf, xrandr -q) seem to differ. And the only difference, now that it works, is, as you pointed out, the resolution in the "Display Preferences". Now that the display is showing right, (and not before) the resolution is in the maximum possible.

Any idea, however, as to why it whimsically changes when you reboot? Any idea as to why sometimes you are logged on with the right sort of screen resolution, and sometimes with the wrong one?

Santiago.

I have the same problem. Toshiba L355-S7915 with 17" screen. Half the time I boot up the screen is set at a smaller resolution taking up half the screen. Other times the display is correctly set at 1400x900. However, even when it boots correctly at 1400x900 it's still messed up. The volume control is placed at the very right on the top bar. Then there is a 3" gap between it and the power on/restart/hibernate button. Next to that is the Wifi strength, and next to that is the date/time.

On the bottom bar I have the double desktop pane on the very right. Then there is a 7" gap to the left of it, then the trashcan. The trash is practically in the middle of the bottom task bar and I can't move it.

Weird.

Bump. Same issues. I can't even get a desktop background to appear correctly on this laptop. If somebody will post me a link to instructions on how to post screenshots I'll upload some.
Thanks.

I've installed Ubuntu on 2 laptops and 2 desktops. This laptop is the worst experience with Ubuntu that I've had. Between semesters I may try the older version of Ubuntu. If it works better, I will post here.
