18.04 issues with screen res on old laptop

Hi All,

I’m new to linux and I require help with fixing some issues. The main one is my screen resolution.

The max res is 640x480 and I hae tried many different fixes and all hae failed. I’e copied what I tried to do late below.

james@ubuntu:~$ xrandr
xrandr: Failed to get size of gamma for output default

HI James (Jimbo).

Firstly can you confirm you installed Lubuntu 18.04; I see only reference to Ubuntu in your posts.

Also I’d like specs about your video hardware. Whilst many commands can provide this information, the command I use is sudo lshw -C video (sudo to elevate privilieges, lshw or list-hardware is the command, class=video to limit the output to video hardware; an example of another command might be lspci -v -s $(lspci | grep ' VGA ' | cut -d" " -f 1) but I find the lshw easier to remember). If the detail was already provided, sorry I missed it.

The commands you used to get/list information can also be handy, as different commands present the same information slightly differently (eg. the two commands I used to list your video hardware) and knowing the command helps orient the reader to what should be expected.

Welcome to the community

Hi guiverc,

I can confirm that I am using Lubuntu 18.04.

After using lshw the following was displayed.

`*-display UNCLAIMED       
       description: VGA compatible controller
       product: CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro]
       vendor: VIA Technologies, Inc.

       bus info: pci@0000:01:00.0

Thank you for the commands you’ve taugh me so far. So please keep them coming :smiley:

The “CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro]” from that command tells you what your video card reports itself as to the linux kernel, the UNCLAIMED tells you the kernel didn’t know what to do with it, thus it’s ignored (why you have such low resolution).

I don’t know/remember the card; but recall S3 as really old though, I did a search using that and Ubuntu (startpage for me) and scan down for a site I ~trust


The answer given I don’t see as harmful, it exists in bionic (18.04, ie. https://packages.ubuntu.com/bionic/xserver-xorg-video-openchrome) and may fix your issue so I suggest you try it, ie.
sudo apt install xserver-xorg-video-openchrome
(I try and remember or keep a feel for the packages the command installs) then reboot and hopefully it’ll be fixed.

If it doesn’t help, just remove it (sudo apt remove xserver-xorg-video-openchrome) and you’ll be asked for confirmation. If the packages listed to be removed are the same ones (to the best of your memory) that were installed, you answer Y to actually remove them, and reboot. If you’re here - you’ll be back where you started, but I’m hoping the prior paragraph worked :slight_smile: as I saw confirmation from another user at https://ubuntuforums.org/showthread.php?t=2391978

Quick update! I fixed it just before I saw your post. I came across a ubuntu forum page, which contained someone script for a simial issue. The script contained a OpenChrome Graphical for VIA Driver.

Here are the results:

james@ubuntu:~$ sudo xrandr
    Screen 0: minimum 320 x 200, current 1024 x 768, maximum 2044 x 2048
    VGA-1 disconnected primary (normal left inverted right x axis y axis)
    FP-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
       1024x768      59.92*+

I’ll place the link below.

Now I do hae another issue (not including the one key on the keyboard not working, lol). The WIFI is displaying as a network card but lubuntu again is ignoring it. but I’ll leae it for now and raise another page for that.

Many thanks again for your help and your wisdom!
