Ubuntu 15.04 desktop

There is no registry. There is dconf which is kinda similar but doesn't contain information about installed packages etc.

If you run:

sudo apt-get auto-remove

The system will remove orphaned packages. If you run:

dpkg -l | grep ^rc

What is the output?

Hello,

I ran the above command but said there was no command for auto-rumove.
i tried it using just autoremove and it worked but nothing happened as a result.

I ran the second command and the output is this:

Any help with this would be apreciated.

Thank you,

OK let's make Bash do the work:

sudo dpkg -P `dpkg -l | grep ^rc | awkward {'print $2'}`

Should clear some space. The 'rc' bit means removed but residual configuration files are still present.

Sorry. Change the word awkward to just awk.

Stupid autocorrect.

Hello,

Thank you for the answer but I am still having the problem.
Never did this before and did not do it with previous versions.
The desktop is still being inverted at the log in screen.

What happens is, the computer goes through it initial start up phase and then
goes to the second screen where I put in my user password.
Once I press enter, I get almost a small screen shop of an inverted photo of the desktop
going across the screen. It appears only for a second or two and then disappears and
then I have my regular desktop. After I get the regular desktop, everything else is fine.

I have no issues with the OS, it works good. I only have the inverted desktop for a few seconds and while I do not think it is causing a problem, it is just irritating.

I am wondering, can it be a problem with the graphic driver?

Thank you for your continued help.

This sounds as if there is some wrong information transferred from the graphic card to the monitor during initialization.
As it disappears after a second, I would not care too much.

What make and model is your graphic card and monitor? What is the output of

sudo lshw -C display
xrandr

?

Hello,

Here is the information you requested:

First command:

 *-display
       description: VGA compatible controller
       product: G86M [GeForce 8400M GS]
       vendor: NVIDIA Corporation
       physical id: 0
       bus info: pci@0000:01:00.0
       version: a1
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress vga_controller bus_master cap_list rom
       configuration: driver=nouveau latency=0
       resources: irq:28 memory:fd000000-fdffffff memory:f4000000-f7ffffff memory:fa000000-fbffffff ioport:df00(size=128) memory:fea00000-fea1ffff

Second Command:

~$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192
LVDS-1 connected primary 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm
   1280x800 60.0*+

   800x600 59.9
   640x480 59.4
   720x400 59.6
   640x400 60.0
   640x350 59.8
VGA-1 disconnected (normal left inverted right x axis y axis)

I suppose if we cannot figure out what is causing this, we can just leave it alone
since it seems to be working fine and goes away after a second or two.
It is just really strange.
I have had the 15.04 for a while and it has been fine up to about a week or two ago.
All of a sudden, it was doing this.
I am not sure, but I changed desktop wallpapers and downloaded some from a Ubuntu website. maybe it had something to do with that.

Thank you for the help

There is the option to switch from the open source nouveau driver to the proprietary NVidia drivers. Maybe that would change something.

Ok, maybe this is causing the problem.
I was using the NVidia driver at one point but some how it must have changed over to the nouveau driver. I was using this driver before and had some problem with the OS.
When I use the NVidia driver, I do not have any problems.

Is there a way to change over to the current NVidia driver?

I have to say, there was one NVidia driver that really messed up my computer but I do not remember which one it was. I think it was 340. series. There were reports all over the internet that this was a really bad driver.

But if you can help me to switch to the NVidia driver, I think it will do the trick.

Thank you,

What is the output of the command

sudo ubuntu-drivers devices

Output is:

== /sys/devices/pci0000:00/0000:00:1c.1/0000:0c:00.0 ==

This output shows that you could use the NVidia-304 or NVidia-340 drivers.

To enable that driver use the software & updates tool, switch to the tab "Additional Drivers" and select one of the nvidia drivers, see also http://www.omgubuntu.co.uk/wp-content/uploads/2013/04/drivers.jpg

I updated the drover to the NVidia driver. System is working great now, no inverted desktop after signing in.

Thanks for your continued support. I really appreciate it.
