@berkaroad That's sad.
Actually, Kernel 5.10 on the Armbian is quite okay.
But I dont know why when I tried Xonotic, it's very laggy.
I tried to install GPU support by following solution in the webboard.
But still got like 10 FPS.
So, I think updating the kernel could help.

@george 内核启动设置了ipv6.disable=1，今天发现wifi突然断开后无法重连，禁用wifi后再启用也无法恢复，重启电脑后正常。（新问题）

查看日志如下： journalctl -xeu wpa_supplicant

补充一下
使用摄像头为 imx339

输入
gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink signal-fps-measurements=true sync=false
可达到60帧

加上sudo执行
sudo gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! videoconvert ! fpsdisplaysink signal-fps-measurements=true sync=false
只能达到22帧左右

@george Thanks a lot, I will contact the Aliexpress seller

@george It's coming back again.
Thank you so much.

@george that did it, wireguard works now, thanks

@george Thanks for your reply. Local videos from EMMC play well. I am talking about network videos in browser like youtube. Present driver and software ubuntu 24.04 (older kernel) uses almost 50% of CPU just to play a 1080p video. I have an Orange Pi 5b, that has same processor and GPU running orange pi droid (a version of android). That plays youtube videos with much less resources and runs much faster. I am looking for an android version to run on coolpi notebook. Where can I find that? (i have already tried armabian. but did not like that on coolpi laptop. Android for COM5 does not work)

@traceback 兄弟，问题解决了吗？我遇到了一样的问题，还不知怎么处理。

@enok71
I don't have a direct understanding of what happened to this computer, why does it seem to have so many impurities inside.
If you need any information, please send an email to george@cool-pi.com

@george 谢谢 我先试试

flatpak 更换国内仓库（上海交大）：

flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub

@berkaroad 好的，有机会我把背板拆下来看看呢

Flatpak is a good thing for Arm64 ,but may have some problem on CM5

As we know ubuntu on cm5 is using panfork for GPU by patched mesa.
but flatpak has their own mesa without panfork patched.

So some app (like video player or game) install from flatpak can not running with GPU. and Maybe toooo slow.

But for wechat its fine.

@jugg
暂时没有做其他版本的适配。

@George The latest Ubuntu image won't boot from either a usb stick nor if its imaged onto the laptop from my Macbook using ums mode,
both Debian and Arabian boot fine.

@jugg
你是要用U盘刷机吗？最近的镜像是IMG文件，只能使用USB接口连接电脑，通过etcher刷机。
