Hello,
I am wondering if double buffering is enabled in RZ/G2H.
Below are some particulars of the build environment, listing of files in the rootfs.
Build Environment: VLP v1.0.6
Target Image : core-image-x11
Xorg Version : 1.19.3
X is launched with xinit command during boot (through /etc/rc.local)
Related files in rootfs.
# ls -l /usr/lib64
lrwxrwxrwx 1 root root 16 Apr 6 19:14 libXext.so.6 -> libXext.so.6.4.0
-rwxr-xr-x 1 root root 64944 Apr 6 19:35 libXext.so.6.4.0
There is no libdbe.so file.
# ls -l /usr/lib64/xorg/modules/extensions
-rwxr-xr-x 1 root root 236368 Apr 07,2021 11:45 AM libglx.so
Searching for "LoadModule" in Xorg.log results to the following:
# grep LoadModule /var/log/Xorg.log
(II) LoadModule: "glx"
(II) LoadModule: "modesetting"
(II) LoadModule: "fbdev"
(II) LoadModule: "fbdevhw"
(II) LoadModule: "fb"
(II) LoadModule: "libinput"
Since there is no log for LoadModule: "dbe", so I tried to explicitly load the double buffer extension.
Added xorg.conf in /usr/share/X11/xorg.conf.d/ directory with the following contents.
xorg.conf:
Section "Module"
Load "dbe" # double buffer extension
EndSection
After restart, Xorg.log contains the following:
[ 7.347] (II) LoadModule: "dbe"
[ 7.348] (II) Module "dbe" already built-in
It says Module "dbe" already built-in.
Is double buffering already enabled?
Thank you.
