Debian with Chipset SiS 661/741/760

#1 Post by goltrek »

Hi.
I have an old computer with the following configuration.
Processor Amd Sempron 3000, 2 Gb memory with Chipset SiS 661/741/760.
I installed Debian 11 LXDE 64 bits but the resolution is only 640x480 with driver vesa.

Before installing Debian, I installed Xubuntu 20.04 and have 1024x768 resolution with driver fbdev.

How to get resolution 1024x768 with Debian?
Thanks!

Scrub that! It looks like the driver for this was dropped by Debian years ago.

viewtopic.php?f=7&t=121801

Maybe try Antix: looks like they might have a driver:

PCLinuxOS still supports SIS, according to some posts.

Hi Frank.
PCLinuxOS still supports SIS, according to some posts.
It's true PCLinuxOS has a specific driver for this SiS model.
I've already installed PCLinuxOS and the driver really works very well and with the right resolution for the monitor.

See the features:
PCLinuxOS Xfce 2021.02
Motheboard PCChips A33G, Chipset SiS 661/741/760
Kernel 5.9.16-pclos3
Xorg 1.20.10
Driver: sis, v4l
OpenGL renderer: llvmpipe
Resolution 1360x768 @ 60 Hz

It won't help I'm afraid. I thought the driver might be missing some firmware, but there is no driver. Debian is falling back to something very, very basic to give you screen output.

Debian 10 and Debian 11 boot Xorg with vesa driver, resolution 640x480.
Xubuntu 20.04 starts Xorg with fbdev driver, resolution 1024x768.
Not understand why the difference?

Arch appears to have a driver for sis with interesting comments and links:

The Xorg fbdev driver needs a framebuffer /dev/fb* to be present. Maybe you need to load the "sisfb" module to enable the SIS framebuffer. Old-style framebuffer drivers are blacklisted in /lib/modprobe.d/fbdev-blacklist.conf.

Test : stop Xorg, run

Code: Select all

modprobe sisfb
restart Xorg.
If effective, add "sisfb" to /etc/modules and reboot.

Hi PH, thanks for the tip. I'm not experienced user.

I have some doubts.
How to stop Xorg?
How to restart Xorg?
How to add sisfb?

Close all graphic sessions.
Press Ctrl+Alt+F1 (or F2, F3... F6 depending on your setup) to switch to a text console.
Login as root (or user and use sudo/su).
Stop the display manager with either

Code: Select all

systemctl stop display-manager
systemctl isolate multi-user
telinit 2
Load the module and check a framebuffer device is present

Code: Select all

modprobe sisfb
ls /dev/fb*
Restart the display manager with either

Code: Select all

systemctl start display-manager
systemctl isolate graphical
telinit 5
and open a graphic session. If it works, open the file /etc/modules in your favorite text editor (NOT word processor) as root, add a line containing "sisfb" and save.
