[Bug 1877246] Re: Bluetooth midi controllers aren't working
So I can't remember if this worked on Ubuntu 18.04 I think it did but it definitely worked on my Manjaro linux installation and I used it frequently. I would connect my Bluetooth midi keyboards to Linux and aseqdump could be used to list midi devices out and capture midi notes there was no extra configuration required other than pairing the device with Bluetooth. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877246 Title: Bluetooth midi controllers aren't working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1877246/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

A nice safe way of getting sound to work is to install "linux- oem-20.04". This will install a 5.6 kernel for you and sound works.

After upgrading to 5.6.0-1011-oem it seems sound is back without the alsa change above. This will take you away from the 5.4 kernel shipped by default on ubuntu - use at your own risk. You will have to periodically check for and install newer versions on your own after installing this. sudo apt install linux-image-5.6.0-1011-oem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It seems like my sound stopped working recently after an update. Is anyone else experiencing this?

[Bug 1877246] [NEW] Bluetooth midi controllers aren't working
Public bug reported: Hi there, I have tried to use two of my bluetooth midi controllers and neither have been picked up as midi devices after pairing. "aseqdump --list" doesn't have any midi devices listed. If I plug the devices in using USB I do get listings. Not sure how to debug this further as previously this just worked.

[Bug 1873083] Re: Lenovo Yoga C940 frequently does thermal shutdown
I was having thermal issues in Linux all the time before I updated the BIOS: You can only update the bios with Windows. https://support.lenovo.com/gb/en/downloads/ds541233 I used a Windows tool called Rufus to make a bootable windows USB drive. (Tried a number of linux tools to do this but didn't have any luck) I also needed a fast enough USB drive to do this: Samsung BAR Plus USB 3.1 Flash Drive 128GB - 300MB/s (MUF-128BE3/AM) - Champagne Silver Flashed my bios from the Windows USB drive successfully. After the bios update only had issues when the laptop is charging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1873083] Re: Lenovo Yoga C940 frequently does thermal shutdown
I also have the same issue - using ubuntu 20.04. It happens usually when I have the laptop plugged in to power - maybe the turbo boost or scaling governor changes when the laptop is plugged in to my charger. It usually happens when I am on a video call and screensharing or recording my desktop or running a game like bioshock via steam. I don't have any of the above issues when I boot into windows (first time I have had to use windows in 5 years). I have managed to reduce the problem a bit but not completely by following the enhanced thermal configuration section here: https://docs.01.org/clearlinux/latest/guides/maintenance/cpu-performance.html Enable DPTF in your bios. First run: sudo systemctl status thermald.service and note it is missing "Using generated /etc/thermald/thermal-conf.xml.auto" sudo apt install acpica-tools git clone https://github.com/intel/dptfxtract.git cd dptfxtract sudo acpidump > acpi.out acpixtract -a acpi.out sudo ./dptfxtract *.dat Run the following again to see if it worked: sudo systemctl status thermald.service You should now have "Using generated /etc/thermald/thermal-conf.xml.auto" Things left to try: On this page: https://docs.01.org/clearlinux/latest/guides/maintenance/cpu-performance.html Try buid the ThermalMonitor tool https://github.com/intel/thermal_daemon/tree/master/tools/thermal_monitor Seeing if changing the scaling governor makes a difference: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver shows powersave while charging for me but I may have changed it with echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor Disabling turbo boost might help but haven't tried it yet: echo 1 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1873083/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
