Setting "AccelMethod" to "EXA" in xorg.conf -> all characters are OK Setting "AccelMethod" to "glamor" in xorg.conf -> all characters are garbled/mirrored @Michel: Thank you very much for this hint. @Michel: You already replied to: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1011 Do you want me to confirm the bug on freedesktop.org for PPC64?
Bug#943664: Solution for PowerMac11,2
Hi. On my Apple G5 (PowerMac11,2) hardware acceleration was disabled because of a failed "ring 0 test", resulting in the error "undefined symbol: exaGetPixmapDriverPrivate" According to a note I found on the net "the PCIe-x16 slot is directly connected to the system controller and the other PCIe-x slots are routed through some kind of hub." The "ring 0 test" failure was resolved after moving the graphics card from the x16 slot to the x8 slot. Hardware acceleration now works. Note: For me this triggers another bug: If I run my AMD Radeon hardware accelerated the X11 internal font server shows garbled (sometimes looking like reversed) characters. Client side font rendering (Firefox, LibreOffice, Emacs, sakura) works. My Nvidia card is affected too. Until now I have no soultion for this.
Bug#943664: xserver-xorg-video-radeon 19.1 (ppc64) crash at startup: undefined symbol: exaGetPixmapDriverPrivate
Hi. I assume that the error occurs on the PPC64 system because of disabled HA (Hardware Acceleration) too: According to https://bugs.freedesktop.org/show_bug.cgi?id=99851 a "ring 0 test failed" message from drm means that HA gets disabled. dmesg | grep -i drm [5.621228] [drm] radeon kernel modesetting enabled.

In my opinion it would be great if: 1) xserver-xorg-video-radeon_1%3a19.1.0-1 would not fail but fall back to frame buffer device like xserver-xorg-video-radeon_1%3a19.0.1-1 2) the "ring 0 test" would not fail According to the last post from the link above the failure was seen in 4.14.4 and 4.15-rc2 but not in kernel 4.17.2. Maybe I should get/compile a linux 4.17.2 kernel. Thank you and best regards, Ralf
Bug#943664: xserver-xorg-video-radeon 19.1 (ppc64) crash at startup: undefined symbol: exaGetPixmapDriverPrivate
Package: xserver-xorg-video-radeon Version: 1:19.0.1-1 Severity: grave Justification: renders package unusable Dear Maintainer, on the ppc64 architecture the package xserver-xorg-video-radeon_1%3a19.1.0-1_ppc64.deb crashes the xserver at startup. Xorg complains about an undefined symbol: exaGetPixmapDriverPrivate The bug occured after an update from: xserver-xorg-video-radeon_1%3a19.0.1-1_ppc64.deb to:xserver-xorg-video-radeon_1%3a19.1.0-1_ppc64.deb To make sure the bug is in xserver-xorg-video-radeon 19.1.0-1 I switched several times between these two versions of the package. As soon as version 19.0.1-1 is installed, Xorg runs well.
