Porteus

No Need to build that SIS package .... I think I am going to possible use Porteus as a Rescue CD. Wary Puppy is working on that machine .... I might try use that. Thanks for your help.

SIS VGA issue occurred in my old laptop for booting to GUI.
I followed fanthom's solution and I could successfully open xfce v.3.
Thank you for your support.

But when I reboot it, new xorg.conf doesn't seem to work.
I prepared save.dat in USB flash drive before the reboot though.

How can I save /etc/X11/xorg.conf for next booting to GUI?

After creation of a save.dat, a reboot is required before it can be used to store any changes.

Guten Tag @donald!

When I made xorg.conf.new, I booted in Text Mode.
In this case, will the change be stored in save.dat, too?

I thought save.dat is used in Graphic Mode.
Thanks for your help.

Changes cheatcode is active also in text mode. It has not much to do with graphic mode than with text mode. Just follow and read the messages at the screen when you do poweroff at the end of your text mode session.

Bonjour francois!

After writing my previous post, I checked the cheatcode of Text mode
by pushing Tab.
Then I added "changes=/porteus/save.dat" and booted. Save.dat loaded.

I did again the fanthom's instruction with your clear explanation of linux command.
(I am quite new to Linux so linux commands on terminal base are like a new language.)

Now I can boot to GUI! I rebooted twice and confirmed the changes have been saved.
I'm going to use XFCE v.3.0 as brokenman asked me why I stick to v.2.1 and
recommended updating.

Thank you and all of you who replied to my question.

I would like to summarize what I have done to solve SIS VGA problem
to boot in Graphics mode with Porteus xfce v.3.0 i486.

I created USB flash drive using Unetbootin.
Boot it in Text mode.
Login: root
Password: toor
Type following command posted by @fanthom and @francois. xfce successfully opened!
In the System section of Application menu,
Click "Porteus save file manager and creat "save.dat"
Edit a line of porteus.cfg located in /mnt/sdbx/boot/syslinux/
"changes=/porteus" to "changes=/porteus/save.dat"
Reboot Porteus.

Now again select Text mode by arrow key and push Tab key in order to
see its cheatcode.
Add "changes=/porteus/save.dat" (I created "save.dat" in porteus folder.)
Enter to boot.

Type following command posted by @fanthom and @francois. Reboot the system and select Graphics mode.
Voila

I hope it will work for someone new too.

It was written as "xorg.conf-new" but mine was "xorg.conf.new".
If there is something missing, please correct me.

Thanks for summarizing your solution. Good job!

It would be good that mrushton have a look on it.

@francois Thanks for your comment!

I hope mrushton will have a look on it too.
Do you think it's better to send him a PM or e-mail to notice this solution?
I am not familiar with forum's rule yet, so please give me your advice on the matter.

I did sent an email to him yesterday nite.

Vous l'avez deja fait. Chapeau! @francois!

@mrushton Posting your reply would be highly appreciated if the problem solves.
