Trying to get >640*480 notebook with sis 771/671

Post by jerryferry123 »

I' trying to get some use out of an Advent 5421 with sis 771/671 onboard video. Fullscreen 1289*768 is possible as puppy linux runs well in this mode and Mint 71.3 xfce and 17.3 mate both seem to run in high resolution with the live cd. After installation, 640*480 seems to be the default and maximum resolution.

Internet searching returns lots of complaints about sis video cards, references to old drivers for earlier versions of mint and plenty of suggestions about changes to make to /etc/x11/xorg.conf. I've tried substituting the xorg.conf from the live session and used sections from puppys xorg.conf but still no success.

Any help in which direction to go would be appreciated.

Try the command...

Code: Select all

lsmod | grep sis
...to determine whether the kernel has access to the legacy modules. If nothing shows up, try...

Code: Select all

sudo modprobe sis
...to enable them. They may not work of course, or they may be inappropriate for your chips, but it won't hurt to try. Log out to the mdm greeter screen to give Xorg another go with them loaded.

Yup, forget LM17. You'll need to go with LM13 instead. It seems LM17 doesn't support this rather old driver. LM13 is an LTS and has roughly 2years of support left.

Once LM13 is installed, you'll want to follow http://askubuntu.com/questions/691600/s ... deo-driver...

It's for Ubuntu 12.04, which is what LM13 is based on. The best you'll get is 1366x768 resolution.

Good luck!

An another choice is to try to make a proper settings using Xranrd like

Code: Select all

xrandr
cvt 1289 768
... the output is something like

Code: Select all

Modeline ”1289x768_60.00” ...............  -hsync +vsync
... make a new settings

Code: Select all

xrandr –newmode  ”1289x768_60.00”  ..............hsync +vsync 
.... add new mode

Code: Select all

xrandr –addmode VGA1  1289x768_60.00
.... replace VGA1 using the right connector
… to test the resolution open Displays or run a command

Code: Select all

xrandr -s 1289x768
If you get the black screen, press Ctrl F2 and Ctrl Alt Del for rebooting the computer.

With Peppermint 6 (same 14.04 base) I had some luck by making my own xorg.conf. The computer was from a friend of mine, an Asus 1201K.

Copy the code below into your editor and save it as xorg.conf. Copy the file to /etc/X11 and reboot the system. If memory serves me well you have to open /etc/X11 as root/administrator.

Just give it a try.

Code: Select all

As baldrick777 already said, you can only achieve that with Mint 13. Because only then you can install the right driver for it, which will unleash all the capabilities of that video chipset.

This is an easy way to install that superior driver, which performs far better than either the default driver or the vesa driver: https://sites.google.com/site/easylinuxtipsproject/sis

The downside is, that you can only use Mint 13 safely for one year. Support will end in May, 2017.
