Hi, I will provide the confirmation (or not!) that this is a complete workaround, along with the same confirmation on the "upstream" ticket I opened for that bug: https://bugs.freedesktop.org/show_bug.cgi?id=106422
Same as Kevin, the hardware is not mine, and I have to wait to have direct access to it to really check that all goes well (the person using the hardware is not an I.T. person, and can only switch it on and do basic things) The test will be done next week (between June 2nd and June 10th) The 'clean' workaround would then be: - edit /etc/default/grub and replace: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=SVIDEO-1:d" - issue sudo update-grub That is to be sure the option sticks even when patched kernels are proposed by the repository. ** Bug watch added: freedesktop.org Bugzilla #106422 https://bugs.freedesktop.org/show_bug.cgi?id=106422 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1682921 Title: sluggish system, kernel errors on Inspiron 1525 Status in linux package in Ubuntu: Invalid Bug description: Starting in 16.10, this machine started taking forever to boot.
