BTW, your video-card has a rated TDP around of 20W. I have one too...

Well, the "glxinfo | grep OpenGL" gives

It claims OpenGL 3.0, but I use the 2.0 for effects.

And "lspci" gives

My experience has been the exact opposite.
I bought nothing but ATi, now AMD, cards for 25 or so years. Installing them in Linux was always a major pain and they did not always work well with one program or another.
Seven or eight years ago the then current ATi card failed and I needed a replacement immediately. I went looking for another ATi card, but the local computer stores only stocked Nvidia based cards. As I didn't have choice I bought Nvidia and I wish I had done so years earlier. Installation is a snap and I don't recall ever having a video problem with any one specific application.

All of them are OpenGL 3.0 (compatibility 3.3) excluding the last one, which is on OpenGL 3.1

The built-in ones are on AM2+ and AM3 motherboards (the RS880G chipset, Radeon HD4250)

The Radeon HD5450 and Radeon HD6450 are still on stock as brand-new in Romania and very used as desktop class video-cards.

Ironically, in one of my Intel min-PC, which is basically like an laptop, Plasma5 works fine with OpenGL 2.0 while support is for 2.1.

You never explained what's not working or what misbehavior you got, maybe you only did something wrong.
I got AMD hardware both r600 and radeonSI hardware and both works good with radeon kernel module.
You need to report the bugs upstream to the software or driver responsible.
https://bugs.kde.org/
https://bugs.freedesktop.org
You can also for some things use the mailing lists for amd graphics but freedesktop should be enough.
You can't report some vague "it doesn't work" and think the packager fixes things, the packager only compiles the software you need to file bugs upstream.

I do, you have one thing right Radeon has a history of bad Linux support but it's history current graphics drivers are great.
I play a lot of games on my AMD laptop.

dugan · 06-22-2018, 04:38 PM

I'm finding it really interesting that:

a) all of the people reporting graphical issues have Radeon cards (both old and new models)
b) multiple people with Radeon cards are reporting not having graphical issues

What happens is something like in the attached screenshot after some random time, needed login/logout to return to normal, and when I reboot the computer KWin disable its effects, claiming they crashed. That happens in standard in the standard install of Plasma5 on -current.

BTW, I explained what happens several times, even in the Requests thread. Also I explained to Eric, in his blog. Several times.

The only time i remember seeing artifacts was when they switched over to Glamor from EXA but that was in KDE4 and i needed to still use EXA for some time.
Have you tried manually selecting EXA? also use DRI2 with EXA
If i drive pass my storage and remember this i will pick up some 3200 hardware, but i don't think i will any time soon.

How much time?

Hours?

Days?

Weeks?

Honestly, I immediately thought of the Compiz issue where you'd start seeing black rectangles after using it for a while (because you run out of video RAM), but I didn't want to jump to conclusions.

Random between minutes to several hours. Max half a day.

And no Compiz here, just the bare and shiny Plasma5 in top of a relative clean -current, with only Chromium, SMPlayer, Libreoffice, PeperFlash and Adobe Flash as additions.

And about video RAM, the icons and effects crash issues manifests also on a Radeon HD6450 with 1GB dedicated RAM.

What I found common is that all affected video hardware are on-board or so called entry level or "desktop cards", which aren't supposed to do gaming but to bring up the desktop.

AND, WHY there is no issue on KDE4 on same computer, in a similar (even as additions) -current installation in another partition?

Alien Bob · 06-22-2018, 05:24 PM

My suggestion would be to attach gdb to the kwin process (using ssh to connect to your computer from another box and run gdb --pid from that ssh session so that you still have legible text in case kwin crashes), and try to find out where the faults are occurring. It may not be kwin at all that is crashing, I've seen reports about KDE and AMD issues as far as 8 years back. See if it is the kernel driver, the X.Org driver, or mesa even.

Darth Vader · 06-22-2018, 05:31 PM

Eric, I will try that.

Another thing. ONLY while using the Plasma5, but really only, in the dmesg appears something like:

Code:

[   54.444309] radeon 0000:01:05.0: texture bo too small ((1680 1050) (64 1) 1 26 0 -> 7257600 have 4096)

[   54.444376] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream !

Same computer, with no Plasma5 in another partition and that message does not appear.

Hello all, I hope you all have a great weekend;

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.

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

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,

A little bit late, but no plasma5 problem here, with radeon hd5750 fanless

RadicalDreamer · 06-23-2018, 01:26 AM

Have you gone to System Settings->Display and Monitor->Compositor, then disabled "Enable compositor on start up?" Also System Settings->Application Style->Widget Style->Configure->Animations->Disable. System Settings->Desktop Behavior->Desktop Effects->Disable. It wouldn't be a big deal if you disabled it all because you can hit "Defaults" button and it will go back to normal.

Darth has made some good arguments to include Plasma 5 into Current so the issues can be sorted out before release of Slackware 15.

linuxtinker · 06-23-2018, 02:14 AM

I think the sooner we can test it in current the better , but what the hell do I know :^)
