Ubuntu 17.04 and NVIDIA GeForce G72M

Asked by Pavel on 2017-04-17

I cold installed Ubuntu 17.04 on Dell Latitude D820 with NVIDIA GeForce G72M Go 7400 graphics card.
When I use the nouveau open source graphics driver then the graphics is very slow
(characters appear in a terminal window slower than my fingers type them).
When I switch to proprietary driver suggested by Ubuntu then I get black screen in X11, (text mode works fine).

Thanks for any help.

Pavel ; Hello;

Did the nVidia driver install ?
what shows:
lspci -nnk | grep -iA3 vga
sudo lshw -C display
dpkg -l | grep -i nvidia*
cat var/log/Xorg.0.log

Where we see the hardware and if the correct driver is installed and what X has to say about the situation .

All in the process

Here is the output:
    http://www.pokyrek.cz/hw/D820/diag_closed.txt
When I go to text mode by Ctrl-Alt-F1
then
startx
starts X11, where I can manipulate windows, but there is no launcher and no status bar.

Thanks for your help

Pavel

Looks like its running that Optimus technology hack.

Did you install Nvidia Prime?

Pavel (pavel-pokorny) said : #4

To install Nvidia Prime I need network connection.
And I have no network with Nvidia graphics driver (and I have no Unity).
So I uninstalled Nvidia graphics driver.
After reboot I enter the password to login
(it looks like everything is O.K.)
and then I get the login screen again
and this repeats forever.
When I go to text mode using Ctrl-Alt-F1 I have no network.

How can I stop the infinite loop after login?

Thanks for your help

Pavel

Pavel; Hey;

I have a small mind, and address one issue at a time . Of 1st order here is to get to the GUI .
As we have:
[code]
How can I stop the infinite loop after login?
[/code]
Indicates that "you" no longer have the authority to access your desk top.
Verify that is the condition.
Show us the output of terminal command :
ls -al .ICEauthority .Xauthority

It should be similar to:
sysop@x1604:~$ ls -al .ICEauthority .Xauthority
-rw------- 1 sysop sysop 13188 Apr 18 13:05 .ICEauthority
-rw------- 1 sysop sysop 50 Apr 18 13:05 .Xauthority
sysop@x1604:~$

Where I am sysop. Is your user name present in both those fields ?
Be aware that the command "startx" is depreciated in most DEs, and has very limited applications .
Maybe likely that you broke "your" access to the GUI ?

we do fault isolation

Can you help with this problem?
