[SOLVED]Bad performance on AMD A4-4355M / Radeon 7400G

I am not very happy with the performance of my sapphire vs4. I can hardly narrow down the cause for that, so probably the best is to describe the behaviour and show my settings.

DE is XFCE. When I set a desktop wallpaper rather than solid color, the bluetooth mouse and the keyboard react very slowly, sometimes I have to switch them off an on again to be able to work with again. On solid color controls work fine. It works already better when having a window on top of the wallpaper, the bigger the better.
Most youtube videos do not work. Other flash videos do work, but after a while they become jerky.  The same happens with playing DVDs e.g. on vlc. Bluetooth sound disconnects when videos go really jerky.
XBMC shows the same behaviour, life streams usually hang up XBMC.

Sometimes but really rarely, all seems to work nice - but that´s the exceptional case. top CPU usage shows 10-20% while watching flash. Sometimes the whole thing shows latency on inputs when accessing hard disk.

Anybody else with a Trinity APU running Arch?

Re: [SOLVED]Bad performance on AMD A4-4355M / Radeon 7400G

I'm running a Llano APU on Arch, and I've gotten better performance with AMD Catalyst than I have xf86-intel-ati consistently on Ubuntu. I never tried the Open Source driver on Arch, as AMD Catalyst pretty much gives me the performance I need.


Claire is fine.
Problems? I have dysgraphia, so clear and concise please.

Re: [SOLVED]Bad performance on AMD A4-4355M / Radeon 7400G

Kodiak, in your 20-radeon.conf file you set EXA as accelleration method.

for southern islands and later chipsets glamor is preferred over EXA, and i'm 90% certain Aruba chipset is one of those.
I suggest you try running with glamor, see the arch ati wiki page for details about how to set that up.

Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: [SOLVED]Bad performance on AMD A4-4355M / Radeon 7400G

According to notebookcheck.com the HD 7400G is based on Northern Islands so EXA should be fine.
Have you tried using no xorg.conf at all?

I removed /etc/X11/xorg.conf.d/20-radeon.conf without any change.

The wiki says:  xf86-video-ati driver-1:7.2.0-1, glamor is automaticaly enabled with radeonsi drivers (Southern Island and superior GFX cards); I have not tried it, since the wiki says EXA is the default and works on "newer" cards, but I will give it a try.

Seems to be very messy, I was not able to install it quickly yesterday. Have you downgraded X-server?

$ cat /sys/kernel/debug/dri/0/radeon_pm_info # without GRUB_CMDLINE_LINUX_DEFAULT="radeon.dpm=1"
default engine clock: 200000 kHz
current engine clock: 200000 kHz
default memory clock: 667000 kHz

I was not able to set the power profile described on the ATI wiki page. I always get the output above. http://www.gpuzoo.com/GPU-AMD/Radeon_HD_7400G_IGP.html says the system clock should be faster. Something wrong maybe here?

Re: [SOLVED]Bad performance on AMD A4-4355M / Radeon 7400G

Some news here:
Hard disk is WD3200BPVT:  http://www.newegg.com/Product/Product.a … llFullInfo ==> https://wiki.archlinux.org/index.php/Ad … Green_HDDs

Hardware-acceleration: https://bugs.archlinux.org/task/37888?p … om=-1+week ==> when turning it off, videos do run but what I guess is, that the CPU is under heavy load so it can not serve the bluetooth as necessary.

No, because I use the latest beta provided by Vi0L0, not the "stable" version.

Re: [SOLVED]Bad performance on AMD A4-4355M / Radeon 7400G

Quick update: I replaced the HDD with a hybrid from Seagate and with software from today this thing runs almost smooth! Mark it as solved.

Edit your first post in this thread and pre-pend "[Solved]" to the title.
