Hello.
I’m using the armsom kernel, u-boot, dtb, but the rootfs is debian12, built from debootstrap (xfce + x11 + lightdm).
uname -a
Linux debian-aarch64 6.1.118-rk3588 #52 SMP Wed Apr 15 14:40:23 UTC 2026 aarch64 GNU/Linux
For the GPU, I installed the libmali-valhall-g610-g24p0-x11-gbm_1.9-1_arm64.deb driver from Releases · tsukumijima/libmali-rockchip · GitHub
I’m getting a yellow desktop (it feels like the color channels are reversed). I’m using glmark2-es2-x11 to test the GPU, but the test animation isn’t displayed on HDMI, only the transparent window. The glmark2-es2 log:
glmark2-es2
arm_release_ver: g24p0-00eac0, rk_so_ver: 10

Could you please suggest me a solution to this problem?
