Just installed 20:04, and 18:04 have not this problem.

The main problem is that the screen don't fill up the display. In the settings --> displays, it says it is a 'Unknown display. The display are a common HP S2231a.

I have a Nvidia gfx Geforce GT 520.

I tried install Nvidias X11-server config, but Ubuntu says there is missing dependencies but it get installed anyway, but does not work at all. Just white content.

In Software & Updates--> Additional drivers have 4 rows,

enter image description here

Number 4 is choosen, and the other 3 row are greyed out, and not possible to select them

I have no idea what manual installed drivers are, and I have not doing anything manual.

What can I do?

joni@HP2:~$ sudo dpkg -l nvidia

Edit. After help from @heynnema I purge the nividia-driver and ubuntu use Noveau-drivers

I tried just now to add Nvidias propretarian drivers but get this error message: enter image description here

  • "Unknown Display" usually means a bad cable. Are you using VGA or HDMI, or something else? You "manually installed" the Nvidia server driver, which would be incorrect for a Ubuntu desktop installation. Choose the Nouveau driver, uninstall the Nvidia stuff, and come back and choose "Nvidia proprietory" drivers. Report back. Start comments to me with @heynnema or I'll miss them. – heynnema Sep 23 '20 at 20:37
  • DVI-cable. I can still not select and change driver, even after i have removed Nvidia x-server. /Cheers – joni Sep 24 '20 at 12:10
  • Download the correct Nvidia driver at https://www.nvidia.com/en-us/drivers/results/160182/. Report back. Remember to start comments to me with @heynnema – heynnema Sep 24 '20 at 12:19
  • @heynnema . I downloaded the driver an run as root, but the installee compain rhe X-server or other module was running. Does not an X-server always run, if you have a screen? – joni Sep 24 '20 at 13:30
  • Edit your question and show me dpkg -l *nvidia* – heynnema Sep 24 '20 at 13:33
  • @heynnema here is the output : – joni Sep 24 '20 at 19:04
  • Either edit your question and add the output there with a paste, or use paste.ubuntu.com. – heynnema Sep 24 '20 at 19:12
  • It'ds to complicated. can't tag with code or something :[ – joni Sep 24 '20 at 19:18
  • I fixed it for you. What you do is paste the text, select the text, click on the {} icon to format it to be human-readable. Choose the nouveau driver in Software & Updates. Then, in terminal do sudo apt-get purge *nvidia*, then try to install the newer driver that you downloaded. – heynnema Sep 24 '20 at 19:41
  • @heynnema I can't select anything in Software & updates --> Aditional drivers. Manual installed are marked, and the rest of the options are grayed out. In Synaptic. xserver-xorg-video-noueau 1:1.0.16-1 are marked as installed. Should I go for sudo apt-get purge nvidia directly ? – joni Sep 24 '20 at 20:08
  • Yes, go ahead... – heynnema Sep 24 '20 at 20:09
  • @heynnema It work fine with the nouveau driver. :) So I think I stay here for now. But how is it if you installl drivers and applications manually, do they get updated? Are there no alternative to add another repository/PPA or something instead? – joni Sep 24 '20 at 20:28
  • Yes. What does Software & Updates show now in the Additional Drivers tab? Screenshot it for me. – heynnema Sep 24 '20 at 20:30
  • I have edit the originasal post... It's complicated... :( Can't see how It be before I edit. Thougt I write a header, but don't se it now. And I have to go to bed now. but how it look now are ther, I think. – joni Sep 24 '20 at 20:58
  • You did great. You can always enable the preview mode so that you can see the outcome of your edits. Go ahead and check the first Nvidia driver, version 390, which is the same as what you downloaded earlier. If it all goes as planned, doing it this way will keep it updated for you, and you'll get the accelerated graphics that you deserve :-). Report back after you wake up. – heynnema Sep 24 '20 at 21:02
  • @heynnema . It's a toke some time for me to try activate Nvidias drivers, and It did not work :( I edit the original post whit the error message as screen shot. /Cheers – joni Oct 02 '20 at 15:22
  • It's been a while since we last talked... so I need to regroup where we are... had you purged the previous Nvidia software with sudo apt-get purge *nvidia* and reverted to the nouveau driver? – heynnema Oct 02 '20 at 15:32
  • Yes I did. purged Nvidia drivers. Head from a pal that, Nvidia had a security problem, so Nvida releas an update, that Ubuntu/Debian not really implemented. Changes within -390 version. but I dont know. – joni Oct 03 '20 at 20:25
  • @ heynnema . nouveau drivers work, so I think a new install i better than try to find other solutions. Something in the install can being fut up. Finding out is more work, than make a new install. But I really love the help you give me. I hate fuking with computers, was the main cause I left windows ;) – joni Oct 03 '20 at 20:48
  • I was just about to recommend that very action. Go for it! – heynnema Oct 03 '20 at 20:50
  • :). Left windos in 2004 :) – joni Oct 03 '20 at 20:54
  • Did we ever check to see that your BIOS was up to date? – heynnema Oct 03 '20 at 20:57
  • Cheers and thank for your help :) In a way... better with open source ;) – joni Oct 03 '20 at 21:03
  • You're very welcome! Show me sudo dmidecode -s bios-version and tell me the exact make/model # of your computer. – heynnema Oct 03 '20 at 21:05
  • Computer say : 6.13 – joni Oct 04 '20 at 00:20
  • sudo dmidecode -s bios-version [sudo] password for joni: 6.13 – joni Oct 04 '20 at 00:21
  • How exactly? Out-print of lshw? – joni Oct 04 '20 at 00:31
  • The easiest way is to look on the computer itself. The brand name, and the series name, are usually visible, and the actual model # can usually be found on a label on the bottom (of the laptop). Otherwise, type sudo dmidecode -t 1. With that info, I can go look for the current BIOS version for you. Thanks! – heynnema Oct 04 '20 at 02:46
