I bought a Dell G15 5530, with Ubuntu pre installed. Dell provides a modified version of Ubuntu (kernel, drivers, firmware, tools and default packages installed). The default image has a kernel 6.1. When updating using Dell repos, it install a modified kernel 6.8. It also uninstalled the 6.1 as soon as the 6.8 is installed (which is odd to me, usually, one keeps the previous kernel as well). However, even with their patch kernel and custom nvidia drivers, the issue occurs with kernel 6.8. With nouveau driver, no issue. Some reports that fresh install of Ubuntu 24.10 with kernel 6.11 and nvidia drivers 560 works fine, but it does not work for me. I couldn't install kernel 6.5 (kernel build using mainline tool didn't load).
Issues are : * freeze after 4 to 5 seconds (last timestamp in dmesg log files), this happens most of the time. Using root console from recovery mode in grub allows to disable nvidia drivers (purge nvdia-* with apt) * random freeze after few minutes. More the graphic card is used, the fast the freeze occurs * nvidia driver not being loaded (according to lsmod) * in on-demand mode, offloading to discrete card does not work (using the env var explicitly to perform GPU tasks) * in performance mode, no boot (freeze after 4-5 seconds) or freeze after few minutes * monitors works only at 60Hz if nvidia drivers are loaded For the record, I contacted Dell. They have no plan on working on this issue. This issue is not part of the warranty covering the G15 5530, according to them (but I didn't check the license agreement).
