Intel Corporation 82815 Chipset Graphics Controller driver

marcinblondyn · 03-15-2020, 05:09 AM

Hello,
I have this old intel 3 Compaq Deskpro EN with integrated onboard graphic Intel Corporation 82815 and I have problem configuring xorg.conf on fresh install of slackware 14.2 kernel huge.s

X -configure tells me that Number of created screens does not match number of detected devices.

I need help from more advanced administrator. What steps should I do? Please help, I want to learn how to deal with this problem.

Kind regards,
Marcin

If you run with no config, X is inclined to detect what's there and configure it. If you have historical configurations, it should ignore them.

Have a look at /var/log/Xorg.0.log, hunt around for the errors, and post them with a few lines context.Resist the urge to do a massive copy 'n' paste. I don't want to read it either.

marcinblondyn · 03-15-2020, 10:13 AM

Sure thing, so..

in Xorg.0.log there are two interesting lines:

Code:

[...](EE) No devices detected.
Fatal server error:
[...](EE) no screens found(EE)

in xorg.conf

Code:

Section "Device"
Identifier "Card0"
Driver     "intel"
BusID      "PCI:0:2:0"
EndSection

btw. if I delete config and run startx I have blank screen and on other tty I have grey stripes.

What else could I check?

How to fix exactly I don't know, but the 810 and 815 Intel IGPs are not supported by the i915 kernel driver. Instead the i810 kernel driver is required. Also, 810 & 815 IGP BIOSes do not support standard VESA modes. If you look now I expect you'll not find /dev/fb0. Xorg.0.log probably also indicates no /dev/fb0 exists. With these IGPs I typically boot with VGA=0x120 or 0x121, which puts more (very ugly) characters on a vtty screen than 80x25 text can.

I just tried with a Dell GX150 (815) here on Tumbleweed last updated summer of 2016 that I normally use with a Matrox G400 AGP, and the 810 module doesn't seem to want to load. Last time I tried to use 810 or 815 video was long before 2016. I don't remember having much luck with those IGPs after KMS hit the mainstream kernel. These are the last two Xorg.0.log from trying X minutes ago and only getting black screens:
http://fm.no-ip.com/Tmp/Linux/Xorg/x...0-202003160158
http://fm.no-ip.com/Tmp/Linux/Xorg/x...0-202003160201
Both "feature" "(EE) open /dev/fb0: No such file or directory".

Good luck trying. If that Compaq has an AGP slot, I suggest you try using it instead. Even a PCI gfxcard would probably be better.

My memory was way out of sync with reality on this. Apparently 810 & 815 support got merged into the 915 module, and X can work OK with the 815 and not so ancient servers:

Code:

I'm going to try to upgrade Tumbleweed to current on this box to see if it still works with kernel 5.4.14 and server 1.20.x after I get some sleep.

business_kid · 03-16-2020, 04:43 AM

That driver situation seems like a show stopper, frankly.

There are secondhand pci video cards lying around for cheap on ebay and it might be a quick fix for you.

Current Tumbleweed works with i815 as well:

If there will be no software solution then I will look for old graphic card. BTW What would be the best for pentium 3 512MB SDRAM?
But vesa should work right? Can you help me to configure vesa instead?

Best Regards

If openSUSE both older and newer than Slack 14.2 can work with the xf86-video-intel DDX, and it does, then it should work on Slack just as well. No manual configuration is required on openSUSE, so no manual confguration should be required on Slack either. Just be sure there is no configuration that could override automagic configuration. That means no .conf file in the /etc/X11/ tree should contain any of the following sections if it has content that might interfere:

Code:

Section "Device"
Section "Monitor"
Section "Screen"

Best to just eliminate any such files to start with. 'X -configure' won't do any better than automagic, and is more likely to interfere than to help. Also there should be nothing on the kernel cmdline to interfere either. KMS must not be disabled, and the i915 kernel driver must load normally.

If you're going to install an AGP card, I suggest Radeon 9xxx series would be least troublesome. The higher the number the better. Performance won't be great, but it should be distinctly better than the 815. GeForce AGP, Quadro AGP, Quadro FX AGP and Quadro NVS AGP would probably be better performing options, if you can find one at a right price that doesn't require more power than your power supply can provide. Even PCI versions of the Radeons, GeForces and Quadros should perform better than the 815 at least in some areas.

Damn, I tried Antix and this method worked like a charm. Sad that I didn't saved taht xorg.conf.. On slackware this method ends with complete black screen. Still investigating. What packets should be installed? Could you share your xorg.conf?

As I have already explained, no such file exists in openSUSE (or Fedora), and no such file is needed in openSUSE (or Fedora), just like most top-20 distros. You should try removing xorg.conf before starting Xorg.

If it doesn't help or solve, you should upload to http://pastebin.com/ the entire Xorg.0.log from your attempt so that we may attempt to help find you a solution that doesn't involve installing a gfxcard.

When I removed all files

Code:

rm /etc/X11/*.conf

Startx got me "black screen of nothing but HDD buzz" I swear I heard XFCE4 loading!
I tried to replace LCD with CRT but still same. Damn.

Could somebody help me how to diagnose what's wrong?

mrmazda · 03-21-2020, 06:58 PM

Next I think we need to see a freshly created Xorg.0.log, i.e. without /etc/X11/*.conf or /etc/X11/xorg.conf.d/*.conf that include any of Sections Device, Monitor or Screen.

That (EE) is a red herring. You don't want to use FBDEV except in an emergency for rescue purposes, so it's not a real error if not found.
