BTW, Plasma 5 is fine here so far as I can tell running on a system with Radeon HD 4200 on the motherboard.

Why has everyone ignored this post??? It's one of the few that actually matter in the whole thread.

I've seen artifacts before, it was something in kde4/qt4 theme engine. That was in 2015.
Back then I posted these:

And just like now, there was dugan saying my hardware has failed.
The GPU still runs everything I throw at it, except that now I keep away from kde.

I've been using KDE4 since 2010 and have never seen anything like that.

Your final comment highlights an important point. If you don't like KDE, you don't have to use it. This is FREE software, as in you're FREE to choose whatever you like.

On a completely different note: KDE4 is now in it's 10th year as part of Slackware. Does that mean it's entitled to half of everything?

It's cool, I did not say I have to use it. There are other reasons why I've dropped it.
The point I'm trying to make is that if Mr. Vader can't repro any of that in compiz, xfce, windows or, for example, lumina (qt5) - then it certainly is a kde problem.

Looks like one of the rendering problems caused by glamor that shouldn't be a problem anymore, it had nothing to do with KDE4 it's was a driver problem.

So it's one of X libraries introduced in 1.16 which is supposed to be hardware independent, and the reason why the problem only surfaced in KDE is because other DE aren't making use of that library?
The screenshots were taken on nvidia binary, by the way. Also, I couldn't repro this thing anywhere else, before or after. On integrated radeon it just didn't happen.

In another post here I talked about why I removed KDE5. Those were the reasons again:

1) I have a slow old machine, I mostly use icewm as my desktop, I still use KDE applications like kate, kwrite, kompare and more. The use of QT5 icons makes it hard to use such applications in icewm -- a lot of missing icons.

2) Printing is more complicated; every time I print I had to select paper size and set margins.

3) With sddm I can not customize login display or use remote login.

4) This last point I did not mention in that post. Anytime shutdown or reboot were done, the output from those shutdown scripts went to tty7 and display is at tty1. So to see those messages (shutdown scripts output) I have to switch to tty7 by pressing ctl-alt-f7.

Again I think Eric is doing a great job - it has to be done, and I certainly hope he keeps working on it. We as users should test and report any problems. The original question was "Is Plasma5 Ready for Inclusion in Slackware?" and my answer: it is not, and then who am I to say this! But that is the direction kde is heading into and we need to stay on top of things.

I have radeon graphic card, I bought it new from Fry's Electronics less than 2 years ago - I wanted to attach a picture but it is too large! - it was on clearance and cheap, I think I paid $50.00 plus tax for it.

Code:

 
root@lazyant:~# lspci | grep -i vga
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]

When I had Kde5 Plasma I had error messages show up in "syslog" that do NOT show up without it now.

syslog with Kde5 Plasma installed (partial):

Code:

No *ERROR* messages in my current syslog!! To be honest I should add that at some point I reverted to xorg server 1.19.6 (including ati driver) and do not remember what x server version I had with *ERROR* messages.

I will look for another hard disk and do another install on it in the same machine and report again.

Thank you all,

Wali

I hope that the Plasma5 fans will note that the author of this post talks about his adventures with Plasma5 while using, guess what? a Radeon HD5450.

Believable or not, these greedy Capitalists sells "defective" budget/desktop video-cards even in America (at least in Phoenix, Arizona), not only in that poor Romania from Eastern Europe.

And I hope that our BDFL and Eric Hameleers will agree with my opinion that they should first make that Plasma5 to run with these budget video-cards, which literally flooded the world and are really usual, before to make it to work on these wonderful Ryzens with 32 cores with 256GB DDR5 RAM and sporting 500W GPUs with 32GB GDDR7 video RAM and worth $1000 only the video card.

My

, for what it's worth...

I moved to Plasma 5 approximately 1 1/2 - 2 years ago, and I haven't regretted it since. I second others' opinions about what a fine job Eric is doing with Plasma, and I truly think it's been at a state for some time where it's fit for inclusion in Slackware proper.

Let's face it, KDE 4 is dead. It was a good DE for its time, but it's time to move on. Change is good, even though we humans have a tough time with change (you know, old dogs, new tricks, etc...)

I don't run XFCE, so I can't speak to the OP's experience, but Plasma 5 has been a very good experience for me. I use a lot of Plasma's features, and couldn't bear to think of living without them.

As for Radeon vs. NVIDIA... In December of 2015, because of AMD's abandonment of the Catalyst drivers, and moving to the direct inclusion of their driver in the Linux kernel,I moved on from the ASUS Radeon R9 270 I'd had since January of that year, to a pair of EVGA GTX 970s in SLI mode. Fast forward to December of 2017: since the games I run show little advantage to SLI mode as opposed to a single card, I moved to an MSI Geforce GTX 1070, and haven't as yet had any reason to regret the purchase, especially since it was before the extraordinary price hike of GPUs in 2018 (I paid $430; in January of 2018, the same card was retailing for upwards of $1k. Insane!)

NVIDIA has not given me any issues on Plasma 5 or any apps I wish to run, FWIW.

Count me in for hoping Plasma 5 makes it into Slackware soon. If you don't like running it for some reason, don't install it! There's plenty of alternatives for those who prefer a different DE (XFCE, Cinnamon, MATE, i3 for those who don't like rodents, as well as a plethora of smaller, lesser known DEs and window managers).

At stack raised to a $1000 worth video card, really, but really really I believe you that you have no problems with Plasma5. Trust me!

So, you suggest to those humble owners of $50 video cards also them to buy a NVIDIA worth of $1000, just to enjoy a modern desktop like Plasma5 instead of the obsolete KDE4, which works fine with their obsolete video cards, BTW?

We now know conclusively that the graphical artifacts are indeed a hardware or (less likely) driver issue. If you're seeing it on KDE 5 and not 4, then it just means that KDE 5 is making calls that hit the defective parts of the driver->kernel->hardware stack, and KDE 4 isn't.

There is nothing wrong with Plasma 5. Time to include it.

I understant that you explain us that the graphics stack from Slackware-current is not ready for Plasma5. I agree, we can consider this way too, could be that the Slackware is not ready for Plasma5.

But, following this idea, while is nothing wrong with Plasma5 (specially when you own a $1000 video card), yet is not the time to include it, because the kernel, libdrm, X.org and Mesa from Slackware does not support yet this wonderful modern DE.

Way back when, in the early days,

I can remember paying well over $300US for ATi cards in the late 1980s and '90s. Factor in inflation and what would be the equivalent prices today?
Fast forward to present day and I don't know what current prices are for ATi cards, but I have yet to pay over $80US for any of the three Nvidia cards I've purchased in the last 7 or 8 years. My current card is based on the GT-740 GPU and came with 2 gigs of video RAM. Never had a problem with any of them. The first one was based on the very basic GeForce-210 and came with one gig of RAM. When the most recent drivers no longer supported it, I went looking for a the 740, but could only find the 730 in the local stores. Several months ago I stumbled upon a great deal on the 740, mentioned above, on the newegg.com website. I don't usually use mail order, but it was too good a deal to pass up.

No, the stack in your rig(s) is not ready for Plasma 5. Everyone else' is. Including Pat's.

You did make a point of ignoring questions about your GPU temperatures (posting your CPU temperatures instead) and whether or not you're using -current and the open source drivers (which you should be), so we can't discuss those possibilities.

Darth Vader · 06-23-2018, 10:55 AM

Not everyone buy $1000 video cards, you know...

At least outside of North America and Western Europe.

BTW, I cannot shown you the GPU temperatures in that post, just because the video-card is included in the motherboard's northbridge. So, you can consider the GPU temperature that "NB Temp" all the way.

Other information I cannot give you about its temperature; blame the open-source AMD/ATI support.

And it 's working on hardware that doesn't cost $1000. Such as the Radeon device that Pat tested it on.
