Hello Gang!

I received, a while back, a CD of DSL v. 0.7 from a friend.  My computer is a Dell Dimension XPS P90 with a 90 MHz Pentium processor and 128 MB of RAM.  The video card is an Imagine i128.  I have a 14k hardware modem and a 56k Motorola Voicsurfr modem.  The CD drive is not bootable and so I use a boot floppy.

I have tried, many times, to have DSL run properly on my computer.  It does boot, however, the display is poor.  If I choose a resolution of 1024x*x*, a grey stipple pattern appears on the background.  Changing style adds colours, but often text is unreadable.  No icons appear on the desktop, nor even the disk with the penguin in the centre.  I am able to get some applications to run, such as Ted and XTetris.

When I boot setting the lowest resolution, the display is coloured, Dillo with an introduction to DSL appears, the central penguin disk is displayed, but there is a colour problem (the splotchy type that appears when two programmes running colours conflict with each other).  XTetris does not run.

Changing colour depth seems to make no difference.

I removed the Voicesurfr modem, just in case a conflict with the sound card were, somehow, the problem.  The result was the same.

These are the error messages that appear when shutting down after booting with the 1024x*x* resolution:

**********
insmod:\lib\modules\2.4.22.xfs\kernel\arch\i386\kernel\apm.o: init-module: No such device

insmod:\lib\modules\2.4.22.xfs\kernel\arch\i386\kernel\apm.o: char-major-10-134 failed  Failed to load groupfile

BScreen::BScreen:manager screen0 using visual 0x21, depth 4

ImageControl::BImageControl: invalid colormapsize 125(5\5\5) - reducing

Gdk-WARNING**: visual typ-static color depth=4, image bpp=4, lsbfirst is not supported by GdkRGB
*********

With the lowest resolution,  there is a series of error messages about failed colour display, upon shut down, that I will not reproduce.

On my friend's machine (which happens to be a higher Pentium with more RAM) boot up with the floppy works fine and DSL seems to run with no problems.

In its current state, I cannot use DSL.  Could it be my video card?  By any chance, has the newest version solved this problem?  On the other hand, is the problem with Knoppix or even Debian, meaning that all distributions based on these, such as Feather Linux, will not work on my machine?

Thank you for any help.

Have you tried both Xvesa and fbdev, if not, try the other one. You could also add -swaprgb in .xserverrc in your home directory; you first have to kill X with crtl+alt+backspace, edit the file and finally run startx.

Some info about the Xvesa server:

try using 800x600

As recommended, I have tried xfbdev instead of xvesa.  This does not work at all. It gives, as error:

 modprobe: modprobe: Can't locate module fb0
 XIO: fatal IO error 104 (connection reset by peer) on X   server "0.0" after 0 requests (0 known processed) with 0 events remaining    .

I also tried xvesa with -swaprgb.  This produced the same colour problems as before.  I will soon try the 800x600 mode and other commands in xvesa.

Thanks for the effort.

I have tried 800x600  resolution and I get the same result as the lowest resolution.

Since, during boot up, I always get the message "You passed an undefined mode number", and trying different modes does not seem to help, I added the -listmodes  argument to the xvesa  command.  This always causes an error and the GUI does not initiate, leaving me with the command prompt.

Adding and deleting various arguments to the xvesa  command does not help.

No.

Do not add "-listmodes" to the .xserverrc file.

Instead, boot into text mode and on a command line, type:

sudo -u dsl Xvesa -listmodes | more

and you should get a list of supported video modes.

I have a toshiba 110CS, p100 laptop with a similar situation.
I can ONLY get 4 mode color out of it,
so no icons or backgrounds.

Many applications will not run at all,
requiring at least 8 mode color.
MC will run, as well at the shells...  thats about it..

Both Xfbdev or Xvesa optons do not seem to help..

Perhaps that is the same trouble you are having with your Dell*..

But according to my specs, I *should* get at least 800x600x256.

Kent,
My laptop uses the C&T 65554 chip and it will do 800X600 with 2 meg ram at 24 bit color, you would think that yours would at least do 256 colors. There may be enough differance between the two though. DSL has always worked well with mine so maybe it's a driver issue with yours, although I thought that there was only one C&T driver.

ke4nt,

You could try compiling the Xchips Tiny-X server, which similar to xvesa and xfbdev but for the chips & tech video boards.

Or you could try out this guy's precompiled binary:

and see if it works any better.

In a further attempt to find a solution to my problem, I tried booting with low colour depth (4 and 8).  This gave simliar problems as before with errors on boot-up as:

"megaraid: no BIOS enabled  WD700C.0  Failed initialization of WD-700.0 SCSI card
line 706: xf86cfg: command not found"

Upon shut-down I get:

"Could not initialize any graphics driver.  Tried the following drivers.
x:
no supported color depth found."

The appearance of the screen is like before.

When trying xvesa  with the -listmodes  arguments from the command prompt with sudo, as recommended by cbagger1, I get an error along the lines of "no password".

Any ideas?

OK, try it again without the "sudo -u dsl" part.
