Xorg not working with TC13.1 on vga std
« on: July 12, 2022, 08:46:22 AM »
I'm using TC to build a VM that should work across multiple hypervisors.

With a standard VGA display for a VM (e.g. vboxvga in vbox or vga std in qemu), I'm not able to get Xorg to come up with TC13.1

Here's a snippet of Xorg.0.log -

With TC 13.1, Xorg-7.7 includes both xf86-video-vesa and xf86-video-fbdev unlike TC12.0 which includes only the vesa driver. I believe this was done to support UEFI.

Not sure how to fix the above error.

I tried removing the fbdev tcz so that vesa gets used as earlier, but I get stuck with X not able to find a VESA BIOS -

I see that xorg libvbe.so module is not included with xserver unlike previous TC/Xorg versions. Is that the reason for the above? I tried copying libvbe.so from TC12 to TC13.1 but that didn't work - most likely since the xorg-server versions are different in TC12 and TC13.1.

TC12 works fine with just the xf86-video-vesa and libvbe.so included.

I need Xorg (not Xvesa) and want to support both std vga and vmware svga (the latter works fine with xf86-video-vmware included).

Any suggestions on how to proceed or what to try?

vbe was merged into int10, so that's unrelated. Unfortunately no ideas, other than to report a bug against xf86-video-vesa and to use TC 12 in the meanwhile.

The only relevant google result was in OpenSuse, where a Qemu change did this. But you have the same Qemu and different Xorg.
The only barriers that can stop you are the ones you create yourself.

This error seems to be the root of the problem with the vesa driver:
Code: [Select]
open /dev/dri/card0: No such file or directory

A quick search brings up many results, including this discussion for running under the HyperV VM software, which could be relevent. A similar discussion here. Seems to be to do with DRM, which newer versions of Xorg use to access video hardware via the Linux kernel.

Sorry, that's unrelated - that's from modesetting, not vesa.

The latest xf86-video-vesa/xorg-server gave a permissions error on my legacy bios/uefi laptop - this is why xf86-video-fbdev was added.

Have you tried loading the graphics-KERNEL extension to see if the modesetting driver would work?

You could also try wayland/weston, though you’d need xwayland to use the fltk applets.

Apologies for delayed reply.

Adding graphics-KERNEL tcz enables the modesetting (KMS) driver to work.

But Xorg ignores the vga and video boot parameters and sets initial resolution to 800x600. I need a minimum of 1024x768.

I think for now, I'll use TC12 instead of TC13.1

In TC 14.x x86 I tried install Xorg with vesa and fbdev drivers on my HP Compaq T5000.

Both drivers don't work. If I tried old Slax 6  (mach64, vesa and fbdev drivers) works without problem.
I also tried old Puppy Linux and only fbdev don't work. Vesa and mach64 was working.

Is it possible to put both Xorg-legacy and Xorg-current in to the repo?
There should be also xorg.conf-vesa and xorg.conf-fbdev sample files inside Xorg.tcz.

Do you see any errors in the Xorg log?

In vesa driver I got the same what pstavirs posted.

In fbdev I get the same but last lines was different.

There should be also xorg.conf-vesa and xorg.conf-fbdev sample files inside Xorg.tcz.

In TC15_32 and TC15_64 I was able to get working vesa and fbdev driver if I use xorg.conf downloaded from the internet. But when I try exit to comannd line Xorg crush and black screen with green squers appears on LCD monitor. The same behavior is when I run Xorg without Xorg -reconfigure or without xorg.conf.

How to debug this when the only solution is to hard reset PC? I don't use harddisk.

did a quick search for hp compaq t5000 and parkytowers didn't disappoint:

In 2023 I tested Xorg on HP Compaq T5000. Now in 2024 I tested Xorg on HP Thin Client T510.
