svgalib_helper module loads w/ kern 2.6.10 but no /dev/svga

Hi,

I can load svgalib_helper with no problems at all (I have it in /etc/modules.autoload.d/kernel-2.6), but /dev/svga isn't created. /dev/svga_helper/[0-7] exist. I emerged svgalib yesterday.
EDIT: I had "/dev/svgalib_helper/" written, I've corrected it.

This is what I get from dmesg:

Code: Select all

svgalib_helper: Initializing, version 1.9.19
svgalib_helper: device1: vendor:10de id:0326

When I try to run lincity, for example, I get:

Code: Select all

svgalib: Cannot open /dev/svga
Is svgalib_helper module loaded?

I'm using kernel 2.6.10-r4 gentoo-dev-sources and vesafb-tng. Do I need to create /dev/svga manually?

Thanks,

I have this error on my system currently as well.

Why don't you try symlinking /dev/svga to one of the svga_helper/ devices?

Code: Select all

ln -s /dev/svga_helper/<NUMBER> /dev/svga

I'm experiencing the same exact problem as the original post.

No dice.

File a bug on http://bugs.gentoo.org . Last i emerged svgalib, it would create the /dev/svga device node for me. So this is a sort of bug.

Ok, I got a little further.
First off, symlinking /dev/svga to /dev/svga_helper/0 does seem to work, but it's only the start.
The next step is to chmod u+s /dev/svga.
Finally, my problem was due to me trying to run lincity from an xterm as a non-priveleged user. So if you run it as root, or you run it as a non-priveleged user from the console (Ctrl+Alt+F1) it works.
My problem now is once the game starts, it says to press a key to continue. Upon doing so, the game aborts w/ this message on the console:
svgalib: Failed to initialize mouse.

Great job!

This worked with root only; a regular user, no way..

I've tried the same thing but with "7" and it didn't work. "7" should be the default svga terminal (ctrl-alt-f8 ) so there are no conflicts with frame buffer or text console (ctrl-alt- F1 through F6) and X (ctrl-alt-F7).

I didn't get that error, but the mouse wasn't behaving normally (it wanted to stay in the upper left corner). Probably there's some config file with a different mouse setting. I turned gpm off just to see what happens and that doesn't seem to be it. I'm using an IMPS/2 mouse connected to the PS/2 port. I could quit normally using "q" and then "y", I'm indicating this in case anyone tries this game for testing and doesn't want to get stuck.

I forgot that I had done a chmod 777 /dev/svga--that's probably why I could run it as a non-priveleged user.

So you're saying "7" did not work? Did you use "0"?

There's a svgalib config file at /etc/vga/libvga.config with mouse settings. I also use IMPS2 connected to a PS2 port, but specifying that option (nor several others) didn't fix the problem.

Yes, that's how it worked. "7" did not work, even for root, the same error appeared, "Is svgalib_helper module loaded?".

Ok, thanks for the info.

Ever get the mouse to work? I have the left corner mouse problem and editing the /etc/vga/libvga.config file did not help at all.

No. I gave up after a few days of trying w/out any luck.

Thank You. I will probably do the same but if I find a solution I will try to report back here.
