Christopher Penalver: > Without providing which kernels you tested nobody may understand why this > happened. I hadn't finished my testing. But i did test some of the mainline kernels below. I'm not certain that I installed them correctly. I was hoping to get the ubuntu kernels to build to see if I could get a negative result to confirm I'm testing properly. linux-image-4.15.0-041500-generic (no hdmi problem) linux-image-4.15.3-041503-generic (no hdmi problem) linux-image-4.15.18-041518-generic (no hdmi problem)
> Yes, the instructions previously provided. I went to https://wiki.ubuntu.com/Kernel/KernelBisection I then went to https://launchpad.net/ubuntu/bionic/+source/linux in an attempt to install previously built kernels, and installed the packages matching the pattern linux-headers-4.13.0-17-generic_4.13.0-17.20_amd64.deb (685.9 KiB) linux-headers-4.13.0-17_4.13.0-17.20_all.deb (10.4 MiB) linux-image-4.13.0-17-generic_4.13.0-17.20_amd64.deb (19.9 MiB) once I booted this kernel the system didn't modeswitch on bootup. It didn't crash, but I dont' think it was a proper test. Finally I attempted to build from source directly (perhaps I didn't have modules for the kernel version?) I checked out from git: git clone git://kernel.ubuntu.com/ubuntu/ubuntu- bionic.git Now I attempted to follow the linked wiki page from KernelBisection https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel * sudo apt-get build-dep linux-image-$(uname -r) # this didn't work until I enabled the source repos * I have tried adding something like "+test1" to the chanelog in debian.master * I also had to install libusb-dev and libpci-dev perhaps this had something to do with me installing bionic using new minimal install option. I then did fakeroot debian/rules clean fakeroot debian/rules binary-headers binary-generic binary-perarch (which takes 45 minutes) but I only get the ../*_all.deb file. Also, should there be modules files? Sorry for the long post. I figured I had missed some instructions, thats why i asked first. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768139 Title: Kernel crash when booting laptop with hdmi monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1768139/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
