Radeon HD 8730M on HP 840 G1

Hi, I'm trying to use an HD 8730M with an Intel HD4000 on a HP 840 G1.

  • When I instal xf86-video-ati (Open Source drivers) :

    If I do an

    echo ON > /sys/kernel/debug/vgaswitcheroo/switch

    the server won't start, here is the log

    • With Xorg 1.15

      The server seems to launch, I've got a black screen for a second and I came back to my TTY but I'm absolutely unable to do anything, the system is completely frozen and I have to reboot.
      I have no logs in /var/log/Xorg.*.log and ~/.local/share/xorg/
      if I do a

      startx > logfile

      logfile is empty !

    I well initliased my configuration with

    # aticonfig --initial

    and I downloaded the drivers from Violo's repo !
    For both version of Xorg, if I switch to the intel card, it works well.
    I'm launching my server with startx

And my system is up to date !
Does anybody had the same problem ? It may work as showed on the wiki page of my laptop
Where should I report a bug ?
Thanks for reading smile

Re: Radeon HD 8730M on HP 840 G1

I found the solution for in that post https://bbs.archlinux.org/viewtopic.php … 5#p1412995 to make steam work with PRIME ! Performances aren't crazy but it's a lot better than the Intel HD4000 !
I still doesn't know why vgaswitcheroo doesn't work maybe because it's a muxless system !
And I still don't know why Catalyst doesn't work but.. It's closed source drivers so it's difficult to change things.. And to have a solution since there is no logs !

The only last missing thing is the Segfault while launching Emacs with the opensource driver installed hmm

Re: Radeon HD 8730M on HP 840 G1

The only workaround I found is to make a file at /etc/X11/xorg.conf.d/20-intel.conf with

Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
EndSection

And when I need the AMD card I add a .OLD at the end of its name so, the AMD card appears in

xrandr --listproviders

and I'm able to use it. But it's a really strange bug, should I report it ? How can I get the backtrace ? I have no core. file (however, I activated them according to the wiki

Re: Radeon HD 8730M on HP 840 G1

Which driver are you using exactly? I have Haswell HD4600 + Radeon 8750M (also muxless) on my ProBook G1 450. Catalyst works with catalyst-test-pxp from AUR + xorg 1.15, free radeon driver works as well with PRIME, difference is that xorg config files have to prefer Intel IGP and you offload using DRI_PRIME=1 <your app executable>

Re: Radeon HD 8730M on HP 840 G1

Thanks for your answer smile
I'm using the last radeon driver, the open source one

~|⇒ pacman -Qs xf86-video
local/xf86-video-ati 1:7.5.0-1 (xorg-drivers xorg)
    X.org ati video driver
local/xf86-video-intel 2.99.916-3 (xorg-drivers xorg)
    X.org Intel i810/i830/i915/945G/G965+ video drivers

Xorg config files have to prefer IGP ? How do you configure that ?
Have you got a huge performances difference beetwen open source and proprietary drivers ?
Do you use Conky or Emacs (in graphical mode) ? If not, can you try to launch them ?

Re: Radeon HD 8730M on HP 840 G1

Easiest way to make it prefer IGP is to let Xorg handle it, or at least I had no need for any extra configuration. My guess would be that you have leftovers in your config files when you installed Catalyst first, though it's just a hunch. If that's not the case, wiki has all needed configs. Again, chip which has output attached to it should be recognized automatically and preffered over the other one.
Yes it needs to prefer IGP because in muxless systems video output (screen) is attached to  IGP, not discrete card. What PRIME does essentially is offloading graphics from discrete card to integrated card's buffer as IGP is the one who has actual output.

As for performance, I am not a heavy gamer, or at least most of the time  I do not use anything that really requires extra graphics power from discrete card (occasionally give Xonotic a spin, and that's about it).  Therefor I cannot compare performance having no really relevant data. But what I can compare are temperatures, which in case of free driver are substantially higher than those with Catalyst. I'd really love to be able to use free driver on a day to day basis, but I'd rather switch discrete card off than having to listen the fan behaving like turbine all the time.
(P.S. I made a typo in previous message, it's not HD4000, but HD4600, quite a big difference in performance, will fix now.)

Re: Radeon HD 8730M on HP 840 G1

Thanks for your informations ! I forget the idea of using Proprietary drivers ! I prefer using the open sources one.

SO, I'm looking to find why X segafault, and I seen that the bug doesn't appears with Xorg 1.15. So, I may report a bug to this website https://bugs.freedesktop.org ?
Thanks smile

EDIT : I'm thinking that this bug could be related to the need of glamor-egl not avaible with xorg1.16, when I'm trying to install xf86-video-ati-git from AUR, it says me that glamor-egl is missing hmm

configure: error: Package requirements (glamor >= 0.6.0) were not met:

No package 'glamor' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBGLAMOR_CFLAGS
and LIBGLAMOR_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

EDIT2 : My fault ! I moved the glamor.h from /usr/include/xorg ! tongue

I experience the same issues with a Radeon HD 8670M.

Thanks to this I can use the laptop for everyday tasks:

Someone should have to report it. With kernel 3.16.x X server "only" crashed when opening emacs... Since kernel 3.17 I experienced even more issues. When visiting kernel.org with Firefox 33 I had X crash(for example)

Re: Radeon HD 8730M on HP 840 G1

Bug reported and half-solved !
Try the the git version of intel driver https://aur.archlinux.org/packages/xf86 … intel-git/
It may solve the problem but bring some glitches when usng OpenGL applications !
Keep me updated !
