[Bug 1947697] Re: no longer works after upgrade to 21.10 (raspberry pi 4)
This also worked for me. I placed an automatic apt install as part of my github repository for the systemd-zram script for installation. It took me a long time to find this solution. I hope that any other repositories that install zram will take heed of this. I have found that this makes Ubuntu practical for running on a Raspberry Pi 4 with 8 GB or RAM. It prevents hanging when running a large number of processes or having many open tabs in a browser. I now have 2 of my 3 PI4s with 8GB running Ubuntu 21.10. For inexplicable reasons (firmware) the first PI 4 with 8GB will run Ubuntu 20.10, but will not successfully upgrade or boot after a fresh install of the 21.04 or 21.10 OS. Any suggestions welcome (Yes, I need to post this as a separate question). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947697 Title: no longer works after upgrade to 21.10 (raspberry pi 4) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1947697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The zram module is needed. With installed "linux-modules-extra-raspi" it's working fine. ** Changed in: zram-config (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947697 Title: no longer works after upgrade to 21.10 (raspberry pi 4) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1947697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Apparently the zram module (among others) is no longer there by default on 21.10. It can be installed through the linux-modules-extra-raspi From the release notes: Various kernel modules have been moved from the linux-modules-raspi package in order to reduce the initramfs size. This results in several applications (most notably Docker, bug 1947601 18) failing due to missing kernel modules. To work around this: sudo apt install linux-modules-extra-raspi Hopefully this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947697 Title: no longer works after upgrade to 21.10 (raspberry pi 4) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1947697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello, thank you very much for your answer. Unfortunately, the new version also does not enable zram. At the moment there are several kernel problems (rpi on 21.10). Maybe I should wait until the 8th of november. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947697 Title: no longer works after upgrade to 21.10 (raspberry pi 4) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1947697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, I have updated zram-config package using multi-stream rather than separated devices, it should avoid breaking on CPU with many cores (I don't think this is your case) as well as improve performance.
