    • RE: GenBook-RK3588 Crowdfunding projects

      DDR5 应该是 CM5 的那个新版模块集成的吧,也就是说会有新模块,到时候单卖吗?

      如果我没理解错的话这个众筹版本应该算是“正式版”?现在能买到的 notebook v20 其实算是一个“原型机”或者“测试版”?这个版本和现有的 V20 有多大区别?mainboard 也有变化么?还是只有 cm5 的核心模块有变化。

      目前的 38Wh 电池的确是有点小了,能大一点最好。TPM 我觉得应该搭配 UEFI 支持一起上才会有价值。就跟国内前一阵卖的那个什么“幽兰代码本”一样。

      整机功耗的确有点高,大部分时间是 10w,扛不住 4 小时,体现不出 ARM 的功耗优势,不知道是硬件优化还是软件优化?

      提几个建议,不过考虑到这个机器用的也是 chuwi gemibook x pro 的那个模具,有些可能也不太容易改进,但如果能做到那自然是最好的,能改就改,不能改也没办法。

      1, 增加键盘背光,这个键盘应该是可以上背光的。
      2, 触摸板能换成玻璃材质的最好。
      3, 改良机身强度,目前打字会明显感觉中间是空的,容易下沉,轻轻一按就形变了,部分键帽的导电胶也会存在受力不均匀,有时候按了一下没识别。不一定要金属的,换个结实点的材质也未尝不可,我看 PInebook就很结实。
      4,加个指纹识别(我看主板上有排线插口),不过感觉也没地方放,但是 chuwi 有个模具用的键盘是一样的,电源键带指纹。
      5,加个麦克风,目前机器上的麦克风孔没用上。
      6,铰链换个能单手开合的,目前这个有点紧了

      最后价格多少啊,感觉挺喜欢这个本子的,都拿来当主力机用了一阵了,32G大内存还是很爽的,不太满意的重点就是键盘和功耗,突然升级这么多有点感觉被被刺了。不知道哪些更新可以用买配件的方式给升级上。

      还有就是个人建议去 indiegogo 众筹,或者给一些 linux 社区之类的发发广告,老外应该买的人不少。很多当年用 pinebook pro 的人想要 3588 的本子,这个应该是个不错的代替。

    • RE: Firefox deb version freezed when try to play video

      Just uncheck "Use recommended performance settings" and "Use hardware acceleration when available" in Firefox settings will fix this issue.

      But also will have no GPU acceleration.

    • After suspend scaling_max_freq set to lowest. and some perfomance tweak

      I set CPU scaling_governor to schedutil for powersave.

      echo schedutil > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
      echo schedutil > /sys/devices/system/cpu/cpufreq/policy1/scaling_governor
      echo schedutil > /sys/devices/system/cpu/cpufreq/policy3/scaling_governor
      

      I found after laptop wake up from suspend.

      /sys/devices/system/cpu/cpufreq/policy1/scaling_max_freq
      /sys/devices/system/cpu/cpufreq/policy3/scaling_max_freq
      

      will be set to lowest 408000. That makes laptop quite laggy.

      Maybe its a bug in Kernel?

    • RE: Intel AX200 / 210 working on laptop?

      Just got my ax200 and installed.

      The kernel notebook v20 using doesn't include iwlwifi module.

      Have to compile with iwlwifi enabled.

      sudo apt-get update
      sudo apt-get upgrade
      sudo apt-get install git 
      git clone https://github.com/yanyitech/coolpi-kernel.git
      sudo apt-get install flex bison libssl-dev
      sudo ln -s /usr/bin/python3.10 /usr/bin/python
      

      edit deconfig and enable module.

      coolpi-kernel//arch/arm64/configs/rk3588_cpcm5_notebook_v20_defconfig
      

      add

      CONFIG_IWLWIFI=m
      CONFIG_IWLDVM=m

    • Fix "Disable Touchpad while typing" not working

      Cool pi laptop Ubuntu system use libinput to manage touchpad and keyboard.

      But "Disable Touchpad while typing" is not working. That's because keyboard is on the USB bus, And this feature will not woking on USB keyboard but only internal one.

      You can create /etc/libinput/local-overrides.quirks:

      [Cool Pi Laptop Keyboard]
      MatchUdevType=keyboard
      MatchBus=usb
      MatchVendor=0x1C4F
      MatchProduct=0x06B
      AttrKeyboardIntegration=internal
      

      Reboot laptop ,and "Disable Touchpad while typing" will work perfectly.

      See:

    • RE: Firefox deb version freezed when try to play video

      Upgrade finished, Seems boot up speed much faster than before.

      Will play around with fedora image.

      BTW I compiled kernel 6.1 from github https://github.com/yanyitech/coolpi-kernel kernel 6.1 branch and It can't boot up.

      Hope new kernel will come soon.

      Many thanks for your help.

    • RE: Firefox deb version freezed when try to play video

      @george Nice, I'll try it.

      Btw I finally figured out why my USB Disk can't boot up.

      The the fedora image you gave me have Boot up info in cmdline like this:

      rootfs=LABLE=writable

      And my EMMC also has a parttion labled writable(dafault).

      So actually it booted up from usb disk, but set writable lable on emmc as root, So I boot back to my ubuntu. That mislanding me ths USB disk can't be boot up.

      I changed to rootfs=UUID=(my usb disk UUID). And I can boot into fedora image now.

      @george I knew that.
      But the point is I can't find a usb stick to make this fedora image boot up.
      Wiki said only usb 2.0 disk can be boot up.

      I tested all my usb 3.0/2.0 devices. Only one usb 2.0 stick can be booted. But it's 16GB, fedora image is 17GB and can't write to it.

      I just asked you to recommand a usb device can be boot up.

    • Intel AX200 / 210 working on laptop?

      The default wifi module is RT8852BE and It have a quite bad bluetooth compatible with my mouse.

      I saw wiki and it said AX200 can be replaced on this board. Just plug in to m2 slot and git clone firmware from intel to /lib/firmware/ to make it work. that's right?

      But how about ax210? I think it may not working because the low version of kernel (5.10)

      Could you tell me what's the type of RTC battery connect pin?

      1mm? 0.8mm?

      I'd like to have a try.

      @george So is it possible to disable hardware decoding in firefox, and this may fix this issue?

      @george
      I already tested.

      cat  /proc/driver/rtc
      

      works quite well, but its UTC time.

      after

      timedatectl set-local-rtc 1 --adjust-system-clock
      

      System dateime will sync to UTC with out +8 beijing region.

    • Fedora system image? EDK2 UEFI support?

      Is it possible to have a fedora 40 system image?
      Ubuntu 24.04 is fine but snap sucks.

      Fedora have offical arm64 version:
      https://alt.fedoraproject.org/alt/

      pinebook pro can also install fedora
      https://nullr0ute.com/2021/05/fedora-on-the-pinebook-pro/

      I tried to make a fedora live boot system like here said:
      https://cool-pi.com/topic/222/customize-any-linux-distro/6

      but system can't boot up with black screen.

      But the way. Will cool pi have EDK2 UEFI support?

    • Cool pi Laptop v20 初步印象

      Since Chinese is my native language, I will write in Chinese. You can use ChatGPT or Google Translate to translate and understand this.

      首先感谢论坛里的 George,还有淘宝客服,以及 B站的“大法师”(Jack)对各种问题的热心回答。

      接下来说说感想:

      1,笔记本的做工比想象中的要好很多,用的模具和 Chuwi gemibook X pro 是同一款,可以看得出来是在那个机器的基础上进行了修改而来,除了机器内部有点空,让打字键盘感觉有“空腔”的感觉之外别的没什么不好。我觉得唯一不好的地方就是键盘没有背光,这个有点可惜,明明主板上有插背光的排线。还有就是触摸板不是玻璃的,有点影响质感。

      2, 笔记本默认的屏幕面板是华星光电的,色域说实话很一般,NTSC 50%,而且明显发蓝,观感只能说“可以忍受”,但是这个笔记本可以很方面的换屏幕,扣开 B 面拆了屏幕就可以换了。我就更换了一个 100% SRGB 色域的 BOE 的 1080P 的屏幕,型号NV140FHM-N66,观感一下子好了很多。原来想直接换 4K 的,但是怕续航顶不住,就没换。换 4K 屏幕也是需要更换 40pin 的 edp 排线的。

      3, 笔记本的性能十分可以,跑 Linux 日常使用的话和我的 Intel 笔记本差距不太大,RK3588 的确比较能打,而且重要的一点是这个笔记本是少有的在 Linux 下可以实现“休眠”功能的。之前玩过 Pinebook Pro, 性能且不说,光一个系统休眠功能就折腾了好几年也没解决。对于一个 Linux 笔记本来讲,能“合盖休眠”,就大大提升了便利度。

      4, 默认的系统是 Ubuntu 24.04,官方已经调整好了 GPU 驱动,到手大部分功能都是可用的。虽然也有 Armbian 和针对俄罗斯的 Alt Linux,但是 Ubuntu 近几年强推 Snap 让人很恶心,我这个也是删了半天才把 snap 删光,希望官方能提供 Fedora这样更为接近上游和 Gnome 原生的发行版。我自己尝试创建了一个 USB 的 Fedora live 盘,启动黑屏。顺便不知道未来能不能支持那个 UEFI 的启动固件。

      5, 笔记本的续航看使用需求,虽然是 ARM,但是 RK3588 本身就是电老虎,功耗全开的话不比一些低压 U 功耗差,官方在镜像里直接把调度策略拉满写成 performance,我测试了一下 ondemand 之类的发现也没省多少电,估计没什么影响,续航轻度使用大概能有 4-5 个小时吧。

    • Firefox deb version freezed when try to play video

      Ubuntu 24.04 with firefox deb version from mozilla ppa.

      Everything works fine except video playing on youtube .

      whole firefox browser will freeze and I had to kill it.

      Here are some logs from terminal:

      GFX1 TextureHost creation failure type=4
      VideoBridgeParent receives IPC close with reason=AbnormalShutdown

      But video playing works well under chromium browser. Or maybe works well on snap version firefox? I can't remember.

    • RTC battery on board?

      I saw there is an RTC battery slot on mainboard.
      Is it possible to add a RTC battery on it?

      cool pi laptop with ubuntu 24.04 seems won't save datetime after powered off.

      checked /proc/driver/rtc it works fine but won't sync to system datetime.

    • Default cpufreq driver: cpufreq-dt or cpufreq-rockchip

      Cool Pi CM5 Laptop 运行默认 Ubuntu 24.04 镜像,觉得整机功耗有点高,没有体现出 Arm 笔记本的续航又是,看了下发现 cpufreq driver 是 cpufreq-dt ,而且默认调度是 performance. 后者是可以改一下,但对于 rk3588s 来说更好的 cpufreq driver 不应该是 cpufreq-rockchip 么,这个如何修改?需要自己编译一下内核?
