With lates update and with kernel 5.12.14 intel graphic eDP-1 black screen
 
After latest system upgrade and with new kernel 5.12.14 the system don't activate display over eDP1, but other external connections work (e.g. display over HDMI).

I use Slackware current on HP Elitebook 840 G5 for a while
and didn't had any problems.

The system boots and the last line wich is visible over the main display is:

Code:
[    6.487831] fb0: switching to inteldrmfb from EFI VGA
the system boots up but with no screen on the main display.

After changing 'vga=normal' to 'nomodeset' in elilo.conf I can get into the console but can not get up the graphic mode.

I need any suggestion how to fix the issue.

Why have you posted the same issue twice? (See https://www.linuxquestions.org/quest...p1-4175697248/)

I can not confirm this. I also have intel UHD620 graphics in my laptop.

But there is a considerable amount of time (half a second, maybe) where the screen is black during booting, that I think wasn't there before the

I truly fail to understand why anyone having problems, real or imagined, with any Integrated Graphics, would continue to employ them when (especially after what appears to be so many reporting kernel issues, real or imagined) they could eliminate the issue with a ~$30 expenditure. How many hours is anyone willing to waste hunting down (apparently continuing) kernel/graphics issues before 30 bucks is just cheaper?

How does $30 fix the issue?

It was by mistake.

I didn't think that it would cause hours of research, rather just some advice from experts.

I'm working with external displays.

Maybe next upgrade will resolve the issue.

Separate non Intel GPU.

I do sympathize with what appears to be a simple solution. I've just noticed quite a few posts involving problems with Intel IGP. That is fairly universally important. Less universal perhaps are thermals. CPUs without IGP or with them turned off, run cooler and so does the GPU. I like cooler.

enorbet, how do I put an additional graphics card inside my laptop? (OP also clearly talks about a laptop.)

correction to my post above: the short period of black was also there when I booted with 5.12.13 again just now, so I think it was always there... selective perception.

Black screen also with linux-5.13 in /testing ?

I don't understand why I should spend additional money when the integrated GPU *should* work fine and hopefully will work fine once I get some extra eyes on it and correct the issue I'm having. That reminds me of an old boss I had. Rather than replacing the brakes or tires of his car, he'd just trade it in and get a new one. He'd have car perpetual payments (not sure why he didn't do a lease, but whatever).

We're Slackware users... many of us are stubborn enough that we'd rather find the solution instead of throwing money at it.

But as j12i mentioned, OP is using a laptop, and I don't think you can find an external GPU for $30 or if it's guaranteed to not have other problems.

rastafadud 07-08-2021 03:11 AM
New kernel 5.12.15 update didn't resolved the problem.

It's probably because I rarely use a laptop and when I do it's ancient. a T61P Thinkpad. BTW it used to be a thermal mess, no way one could actually place it on one's lap for any length of time unless cheap birth control was desirable. A nibbler and an SSD got that down to reasonable.

Anyway for that or whatever reason, I didn't then and still don't see that it is clear OP was talking about a laptop. My sincere apologies.

Yeah I'm a Slackware user of 20+ years too so I relate but whether the kernel driver is at fault or Intel's design, the solution could easily be stop messing with Intel IGP where possible. In fact, though they may get it right with further development Intel's new Discrete Graphics card, is apparently incompatible with many system architectures so maybe Intel just has weird ways of handling graphics. That said, on a positive note, the new Discrete unit is apparently an excellent bang for the bux for production work.

Anyway I don't consider buying something better or more compatible just "throwing money" at a problem, especially on items rather obviously designed for very low cost. Sometimes we eat the bear...sometimes....

It's only been in the last 12 months or so that I have seen so many posts here reporting rather severe issues with Intel IGP. I have no knowledge of new AMD integrated stuff.

Just FTR I didn't advocate tossing the entire PC analogous to your boss's auto solutions, just the graphics. Also FTR I made certain my ancient laptop was nvidia Quadro, not Intel. I still prefer Intel CPU but their graphics leaves much to be desired IMHO.

Hopefully answered above in my previous post, excepting discrete graphics pricing. To that I say oh yes one can.... OK I was off by 7 bux but this is nvidia chipset, new and warranteed. I'm confidant that 7 bux can disappear from time to time with sites like eBay.
