Lightbulb Blank / garbled screen round up

Hello all,

The blank / garbled screen issue was one of the top topics last weeks. However, i am still suffering from this issue. So, i want to name all steps that i tried and - please - add items to that list i missed. Thus, this would be a chance for me but also some kind of reference list for other users.

First, my Hardware / Software:
- Athlon XP 2600
- EPoX 8RDA (May BIOS)
- Geforce2 MX400 (64MB, Xelo)
- Enermax PSU, 353W
- Realtek 8139D LAN
- Samsung 120 GB HDD @5400 RPM

- Debian GNU/Linux, sid
- Kernels 2.4.20, 2.4.21 (kernel.org)

Second, my symptoms:
- "nv" driver works pretty well
- "nvidia" (all last four versions) fails
- X error log halts at "setting resolution 1600x1200"
- Blank screen, depending on settings also garbled one
- system does *not* freeze, can reboot and login via ssh

Third, what have i tried / can exclude as prob:
- did BIOS update (from von Apr 11 to May 7)
- ACPI on / off (BIOS+Kernel)
- APIC on / off (BIOS+Kernel)
- AGP off (Kernel, tried all NvAGP options; Patch from nVidia)
- exchanged graphics card (Geforce2 MX 400 => Geforce 256 DDR)
- tested many options in XFree, e.g. IgnoreEDID, ConnectedMonitor etc. and all that named in all previous threads; changed also lower resolutions and colour depths
- tested with kernels 2.4.20, 2.4.21, 2.4.20+pre7; with and without nForce-Drivers
- physical testing of AGP slots ("card really completely inside?")
- "assign IRQ to VGA" on / off
- "init display first AGP / PCI"
- "AGP 8x enabled / disabled"
- Fast Writes on / off
- voltage settings highered, lowered (AGP)
- Timings set to sane values (RAM etc.)
- IRQs forced; devices not needed deactivated (e.g. deactivating IRQs 10 to 12 and so on)
- LAN card set to another slot (no other cards in there at all)
- DRI on / off (Kernel + XFConf)
- MTRR on / off
- checked sane PSU values (esp. +5 and +3.3V)
- checked files and symlinks (e.g. GLX, /dev/nvidia* etc.)
- deactivated USB

I am reading many forums and this one since two weeks and spend *hours* per day in getting the nvidia drivers to work. Module loads, info in /proc/driver is also sane.

Please, especially EPoX 8RDA owners respond, still no idea if it is an EPoX problem (SUpport Germany says it is some other reason....).

I do not have a Windows OS, so i cannot test there, sorry.

Any Ideas, additions etc.?
Me and i think others would be *very* thankful
for any additions to this list of solutions.

Greetings,

Timo

Hello again,

I schould mention also that i am using a CRT and also forced XFConfig to many values (Horz, Vert freqs etc.).
I am using X Window System 4.2. System is not and never was OC'ed. Currently working with only one RAM (Samsung PC-400, 256 MB), working at 166 MHz FSB, but also tried 100 and 133.
MoBo is Revision 1.1.

Sorry for this addition,

Timo

Default You are not alone

I have a similar system and the same problems.
My mobo is the 8RDA3+ and I'm running a 2800+ Barton. and a GeForce4 ti4600.

I too am a Debiant, running a custom 2.4.20 kernel. I have tried compiling the kernel and modules with gcc 3.2 and 3.3, with the same result.

I'm glad you posted I was about to research the AGP voltage on the old 4x AGP, but if none of them work I wont bother.

Although I hate to do it, Im about to install *spit* wiinblows *spit* to see if that works. I shall let you know how I get on.

Have you contacted nVidia at all? I sent them an email this morning, but have had no response yet.

My mainboard is 8rda+ .
After I updated the bios to 0522,
X can load opengl driver(nv 4363) when it could not before 0522.

You can try it . GL

Default RAM

Hi,

Havent tried the BIOS update yet, but I've just recieved my nice new PC3200 RAM today. Swapped out my PC2100 RAM and all problems are belong to someone else.

It's all working !!!

Maybe the chip has problems when the RAM is running at a different speed to the FSB? Perhaps that is what the latest BIOS fixes??

I am a happy bunny. Except for being miffed at nvidia for not answering my emails.

Unhappy 8rda problem, too

Hello there,

I'm suffering this problem, too.

Many weeks ago I found a thread in this forum about the "8rda(+) BIOS/Nvidia/Linux" issue. The poster was definetly sure that the problem is caused by a BIOS update: the BIOS dated 29.01.2003 was the last one known to be working.

When I read this, I contacted Epox support (Germany). They told me that the BIOS developers in Taiwan are aware of the problem and will fix it with the next release.
(So that's the proof that this bug is BIOS dependent since Epox themself have told so.)

Well, there have been two more releases but neither of them fixes the problem. (That's my experience, though.)

Again, I contacted Epox (Germany) and they told me to be a little more patient. *sigh*

What now? My 8rda still doesn't work and I'm sick of waiting. From the threads I read I think that this issue has been fixed for the 8rda+ board, but still no progress for us 8rda users.

And I was really satisfied with this mainboard at first glance...

Greetings

Angry I take it all back

I'm losing patience, urge to swear building.....

Forget the RAM. It doesn't fix it. What works for me (on this boot anyway) Is choosing the option "load optimal defaults" in the BIOS. It seems to break my USB though?

This is so Screwed!!!!

I may send the whole bloody thing back to Germany.

"I think that this issue has been fixed for the 8rda+" Nope, still broken on my 8RDA3+

Default This seems to be a common problem...

Under Windows98 graphics works, you don't have to test it. But sound and LAN don't.
I'll try to update the BIOS tonight, hope it will work.
My MB and memory have the same frequency - 333 MHz - so the problem is not in this. There are also other interesting issues about these motherboards - with ACPI enabled onboard soundcard does not work. If you disable ACPI is works but USB don't. Oh yes, great card
I'll not buy nVidia products anomore!

Default the problem is Epox-specific

Hello Martin,

Epox has already taken responsibility for this issue - IMHO it is Epox specific and not NVidia specific.

And yes, everything just fine in Win9x/Win2k.

Hello K8enspieler,

Do you have any further information from EPoX? If so, please post it here, plz?
I am really fed up w/ this, and my EPoX contact partner doesn't know about an GNU/Linux issue (EPoX Germany).
Also did not find any hints etc. on the known forums linked to by EPoX USA (e.g. AOAforums, nForcersHQ, AMD forum etc.).

I am also interested in a public / private forwarding of the email you received by EPox.

Thank you for your postings,

Timo

P.S. still playing with the thought og flashing my 8RDA w/ an 8RDA+ BIOS - for some this seems to work ;-)
I see my XP 2600 aging before having seen its performance in OpenGL etc. :-(((

Hi all
I have this problem as well. Right now I am running on the 3123 drivers which work quite well except that I can't switch resolutions w/o restarting X and this I know has been fixed in later drivers. But I really wan't a solution to this problem. I have fiddled with the thought of flashing my 8RDA bios with and 8RDA+ bios but have not dared do it yet since I have read on other forums about ppl frying thier mobos that way. I am very interested in the response from EPoX too.

Yesterday I flashed my BIOS with the latest one (dated 06-09) and nothing changes
This problem is nVidia specific (at least partly) - see: Windows drivers work fine, 'nv' driver from X works fine, but closed-source nVidia driver for Linux hangs. Epox BIOS may be buggy, but nVidia should fix their driver too! I bet other graphic cards work fine with Epox under Linux.

Some people reported here that some versions of BIOS works - which one?
