I've verified that this can be reproduced when booted from a flash drive. As above: extract the 18.04 ISO to a FAT32 drive. UEFI boot it. Create a persistence file and a persistence boot stanza. Boot that.
snapd and Xorg will use lots of CPU. Perhaps not as consistently or as high as when booted from SSD but basically the same behavior. Makes for lots of fan and laggy behavior. Tested so far on the ThinkPad 25, ThinkPad X1 Yoga Gen 1, pre-production ThinkPad X280, and an IdeaPad Yoga 920 with the same results. For the record the X280 needs "psmouse.proto=bare" added to the linux line in the boot stanza to have a functioning UltraNav device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767896 Title: Live 18.04 with persistence snapd high CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1767896/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
