[SOLVED] Pb with Radeon HD 6450

ndesmoul · 2019-06-11 16:38:54

Hello,
To replace an old Nvidia card not supported anymore by Nvidia, I'm trying to use a ATI/AMD HD 6450, but without success.

The driver installed is ATI.
I use KDE/plasma, but at start, after usual console text message, sddm start (?) but I have only a block screen with a mouse cursor.

Stopping the sddm service, I manage to launch KDE with startx, but with a lot of error message (crash of ksplashqml, etc.), and no 3D application can be launched.

Mesa and xf86-video-ati packages are installed. My Arch is up to date.
The radeon module seems to be loaded and used (and nothing is blacklisted in /etc/modprobe.d/).

$ lsmod | grep radeon

radeon               1634304  2
i2c_algo_bit           16384  1 radeon
ttm                   114688  1 radeon
drm_kms_helper        212992  1 radeon
drm                   495616  5 drm_kms_helper,radeon,ttm

First I tried without any specific xorg.conf.
Then with the following one (without more success): /etc/X11/xorg.conf.d/20-radeon.conf

Section "Device"
	Identifier  "Radeon"
	Driver "radeon"
	Option "AccelMethod" "glamor"
        Option "DRI" "3"
        Option "TearFree" "on"
        Option "ColorTiling" "on"
        Option "ColorTiling2D" "on"
EndSection

Using 'lspci -v' I see the part corresponding to my card:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM] (prog-if 00 [VGA controller])

I can't find any error message corresponding to the radeon driver:

So I'm completely at lost at what could be the problem.
But even the most simple 3d application doesn't work:

$ glxinfo

 
name of display: :0

  Major opcode of failed request:  152 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  37
  Current serial number in output stream:  38

Ok. I finally found what was the problem: I didn't see that I still had some old nvidia packages installed from AUR.
Deleting them resolves the problem. All seems to work now.
Sorry for the inconvenience.
