pakt,
Can you test the program "xrandr", attached.
Just type "xrandr" on the commandline, and see if it gives you the vertical refresh frequency.

With 17" external TFT panel connected:

The TFT screen display information shows: 1280x1024 75Hz

SZ: Pixels Physical Refresh
*0 1280 x 1024 ( 342mm x 271mm ) *76
1 1024 x 768 ( 342mm x 271mm ) 76
2 800 x 600 ( 342mm x 271mm ) 73
3 640 x 480 ( 342mm x 271mm ) 73

Changed xorg.conf section "Screen" from "1280x1024" to "800x600" then re-ran X

The TFT screen display information shows: 800x600 75Hz

SZ: Pixels Physical Refresh
*0 800 x 600 ( 344mm x 272mm ) *73
1 640 x 480 ( 344mm x 272mm ) 73


Deleted xorg.conf, shutdown, disconnected 17", rebooted, chose h31.5-48.5v40-70 LCD Panel 1024x768 and 1024x768x16 video mode:

SZ: Pixels Physical Refresh
*0 1024 x 768 ( 347mm x 260mm ) *0
1 800 x 600 ( 347mm x 260mm ) 0
2 640 x 480 ( 347mm x 260mm ) 0


Shutdown, re-connected 17", rebooted using previous xorg.conf:

SZ: Pixels Physical Refresh
*0 1024 x 768 ( 342mm x 271mm ) *61
1 800 x 600 ( 342mm x 271mm ) 61
2 640 x 480 ( 342mm x 271mm ) 61

Still using 17" panel and previous xorg.conf, changed xorg.conf section "Screen" from "1024x768" to "1280x1024" then re-ran X. The resolution defaulted back to 1024x768. I assume this is because Section "Monitor" specified VertRefresh 40-70 and 1280x1024 would require 75Hz (from above info).

SZ: Pixels Physical Refresh
*0 1024 x 768 ( 342mm x 271mm ) *61
1 800 x 600 ( 342mm x 271mm ) 61
2 640 x 480 ( 342mm x 271mm ) 61

Barry, this brings up something else to consider. When I run the xorgwizard with my external 17" TFT panel connected (and xorg.conf deleted), the wizard goes directly to "video mode menu". I don't get the chance to select LCD panel or CRT monitor. That's of course why the 17" ends up at 75Hz instead of 60Hz. The wizard assumes it is a CRT monitor and correctly chooses the highest refresh frequency. Not good in this case as a TFT panel should work at 60Hz...

Hmmm, that's an awkward one, but I don't see it as critical.
Xorg auto-detects the plug-and-play LCD monitor, which is why
the wizard goes straight to resolution selection dialog.
Xorg will only drive the panel at a frequency that it reports it is
capable of.

If you consider 75Hz too high, after the first test, you do get an opportunity to "tweak" the settings, and you can drop the frequency down.

Actually, I have a better idea than having a boot option/kernel parameter to allow users to get Puppy back to normal if X.org freezes on boot.

There could be a script that checks to see if X exited properly and if it didn't then skip loading X at boot and go to console with a message that says what happened and tells the user to type "loadx" to start X again or type "xorgwizard" to change the display settings. I was thinking of something like have a line in a file (e.g. xload) that says X-Loaded=true and have it set to true just before X is started (including the test following xorgwizard) and set to false immediately after X is exited. Then at boot, check to make sure that it doesn't say true. Maybe have a script "loadx" that sets X-Loaded to true and then loads X via xwin and passes on whatever parameters were given then sets X-Loaded to false and exits. I probably repeated myself a bit but oh well. Smile

J_Rey,
That's a good idea.

I'm sad to hear there are problems with the new Xorg wizard with some of you. I tested it with my old non plug and play 17" CRT monitor at the weekend and it worked great.

I ran it to start afresh creating the xorg.conf file and tried to act like a non-technical user. I did not consult my monitor manual and tried to follow the screens. It started X OK but the screen was misplaced so I went into the tweak options. With the old Wizard I had to consult my manual to get frequencies. This time I just increased the frequency to that suggested and it worked although the frequency was not as high as that found when I put the frequency range from the monitor manual in. I've just realised that I knew I had to increase the frequency because of previous experience. How would a newbie know whether to increase or decrease the frequency? This revised wizard is a big step forward. I like X-Org!

Good question!

Very difficult to give a definitive answer...

This might be slightly off the topic of the thread, but have you seen this page about the i810 chipset Barry? It looks a year or two old but may have helpful info. Also this Intel webpage about Linux and the i810 chipset family.

FWIW, 1.0.7alpha with Xorg did sucessfully recognize the i815 video and must have recognized the shared RAM as it offered and ran video resolutions consistant with the full shared RAM. It ran acceptably at 1024x768 with a 75 Hz vert refresh on my i815 based uATX motherboard.

That said, it's still crappy video and virtually any PCI or AGP plug in card outperforms it soundly. If at all possible when faced with one of these boxes, I stuff in a castoff ATI or SIS based card. Pup is happier and so is Dwindles.

I just installed the alpha (with the new xorgwizard.gz and without).
i used a new pup001.zip.
Went good so far, the SIS-card was recognized (xorg).
Just the mousewheel did not work (logitech).
The reason was the protocol, I need ImPS/2 instead of "auto".
As I forgot the correct name I entered IBMPS/2, what caused X to refuse starting (black screen, no reaction).

I finally could fix that by hitting CTRL-C during startup, and editing xorg.conf.
But from now on, xorg did not accept any new changes in xorg.conf.
Ran the wizards several times, switched from xorg to xvesa - but I always got just 800x600.
The wizard told about "nan" -values for the monitor-frequencies, so I added values from other working xorg.conf, I also used complete other xorg.conf I had used with xorg6.8.2 before - but no change, just 800x600.

I have no idea, what went wrong here.
------------------
Now I used the old pup 001 from Puppy 106, and again at first start, Xorg was configured correctly.
I changed the mouseprotocoll correctly now with an editor to ImPS/2 , and now the mousewhell works, and I have high resolution.
But I did not run the wizard again yet...

I will be curious, if I can reproduce that strange behaviour with Puppy 107 beta.

-------------------
Beside this, the Wizard is just great Razz

MU,
Yes, there are many changes to the Wizard since the 15-Dec test version!
