Hello,
I am starting to see garbage left on my screen like the picture below
http://i886.photobucket.com/albums/ac69/CMAR606/LUBUNTU/2014-05-30-234448_1280x1024_scrot.png
That garbage left on the screen ( that clear box) was from me closing
a terminal window
Any ideas why?
And the only way to get it off the screen is open another program a
few times and it clears up on its own.
This is a fresh install from 12.04 to 14.04 I reformatted the pc to 14.04
Thanks,
Christopher
Hi,
I like your background, it is very epic!
What kind of graphics card do you have?
If you don't know you can run this command in a terminal
lspci | grep VGA
Did you install a proprietary driver for it?
Do you have a compositor running (like xcompmgr or compton, etc...)?
If you disable the drop shadows on the windows does it still leave the
shadow?
And finally have you updated you computer fully?
sudo apt-get update && sudo apt-get -y install
I have seen perhaps the same behavior on several machines and also in a
VMWare Player box. In my case the rectangle is always drawn by the
movement of the pointer (like making a selection in a paint program).
In the VMWP box, the rectangle is always translucent. (Not
surprisingly, the card there is "VGA compatible controller: VMWare SVGA
II Adapter.") Sometimes I can click outside the rectangle, it goes
away, and I can continue. I think sometimes that doesn't work and the
pointer becomes ineffective for selecting/opening/running. I have been
able to make that go away and regain control by switching to a different
console and back (e.g. Ctrl-Alt-F1, Ctrl-Alt-F7). Sometimes the arrow
pointer becomes a hand, and I recall that if that happens I never regain
control except by switching consoles. No proprietary driver, no
compositor. And a default installation (like this one) doesn't have
drop shadows, does it? I have just now installed ~ 72MB of updates, so
we'll see.
I have seen the rectangle (but not the hand pointer) on an HP Pavilion
a720n with:
AMD Athlon XP 3200+
512MB
VIA UniChrome graphics with 64MB shared memory
(And I don't have current access to this machine.)
I have also seen the rectangle (but not the hand pointer) on a Dell
Dimension 4300 with:
P4 @ 1.6GHz
512MB
nVidia 64MB GeForce2 MX
(And I don't have current access to this machine.)
On that last machine the rectangle is fuzzy inside instead of translucent.
The last machine also suffers from other graphics anomalies that I wrote
about earlier ("14.04 Look and Feel: many items are VERY faint") and in

The nvidia-96 are simply so old that they won't work with the
current kernel that's one of the reasons it was not shipped I guess.
What actually might work very good for 2D acceleration is the old nv
driver.
But that seems not to be packages for Ubuntu 14.04.
The only source I know where to get it is at launchpad:
http://launchpad.net/ubuntu/+source/xserver-xorg-video-nv
I guess installing won't be enough. It needs removal of nouveau
driver or blacklisting.
The Nouveau driver has known issues with very old cards like this
one. That's the only reason I would recommend the old nv open-source
driver.
This issue with the rectangles is something I'd like to see explained
and hopefully solved, but to date other issues have seemed more pressing.
