Background with cursor after login (new install)

Postby tomasfuk » 2018-02-24 18:18

Hey, I just installed debian-live-9.3.0-amd64-mate, but after login I get just background with cursor. Live version from USB works just fine, problem is only after installing. Any ideas? Thanks

Xconfig Logfiles?
Systemlog?

Which graphic card do you use? Some AMD cards need firmware-amd-graphics package frm non-free repo.

Were there any errors during the installation?

Which session is selected in the login screen?

This output should tell us the default option (run it from a TTY):
Code: Select all
ls -l /etc/alternatives/x-session-manager

boot the installed version, enter this key combo: Ctrl-Alt-F2
do you get to a text login prompt?
if so, login, and enter these commands:
Code: Select all
lspci -k | grep -iEA5 'vga|3d|display' | tee -a systeminfo.txt
uname -rv | tee -a systeminfo.txt
cat /var/log/Xorg.0.log | tee -a systeminfo.txt
if the last command gives a file not found error, try
Code: Select all
find / -xdev -name Xorg.0.log >/dev/null
then try again witht he filename found.

now your challenge is to show us the output.
it is now both on your screen and in a file called systeminfo.txt.
you can use a shell pastebin uploader, or copy it to a usb stick etc.

Hello, thanks for all replies.

Im not aware of any errors during instalation, it went just fine. I did it twice.

VGA is VIA, integrated on MB Asus M2V-MX SE (with coreboot), combined with some Athlon X2, 1GB of RAM and 120GB SSD.

Ctrl+Alt+F2 worked as suggested so I used it to install ssh server, to make this little bit easier. Results of commands are linked below.

that is bad news.
well, some people got it to work.
if you look at the lspci output, you see that there is no kernel module loaded for VGA.
Xorg.0.log confirms that:
Code: Select all
(EE) Failed to load module "openchrome" (module does not exist, 0)

you need to install the VIA driver openchrome.
various packages containing that name might exist; install them all. unless there's a game or browser called openchrome or something.

First, sorry for delay in reply. I had plugged PCIe GPU and just got it working out of box. Since than, PC was off. Today, I decided to remove PCIe GPU and PC working with integrated one. Well, even after removing PCIe GPU, it still works, without any other changes made.

However, following stays in log:
Code: Select all
[     3.746] (II) LoadModule: "openchrome"
[     3.747] (WW) Warning, couldn't open module openchrome
[     3.747] (II) UnloadModule: "openchrome"
[     3.747] (II) Unloading openchrome
[     3.747] (EE) Failed to load module "openchrome" (module does not exist, 0)


Now I have to resolve one more issue: It boots into native monitor resolution, 1920x1200, while maximum resolution suppoted by VIA GPU seems to be 1920x1080. I guest that due to that, picture on monitor is not displayed correctly (left part of picture is displayed at right, right part is at left and black strip in the middle).
I wonder if this is bug somewhere, so it could be fixed for everyone, or if this standart behaviour and I will have to force supported resolution.

i told you, VIA is bad news.
it's also been dead for 10 years; to my knowledge no more VIA gpus are manufactured, so the openchrome driver is only for a few people who still use that old hardware.
i doubt you'll find anyone even remotely interested in actively developing this.
if you search the web really hard, you might find some efforts have been made ~5 years back, and some beta drivers might actually perform slightly better. i know this because i had a crappy amilo laptop with a via chip back then.

Aha, OK. Now it works, kind of, after login 1920*1080 resolution is set and it displays properly. I will leave it like that or I will just put PCIe GPU back.

Thanks
