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).

First experience: Received the laptop in June with Windows 11. Downloaded the version of 24.04 available at the time, and installed it - found it to be very unstable Second experience: I downloaded Ubuntu Desktop 22.04 (probably .3 or .4 with the 6.0 or 6.5 kernel) and installed that instead, and it was much more stable. The 22.04 distribution was also the version tested and certified by Dell and Ubuntu, so I decided to go with that instead. Yay, problem solved - or so I thought. Third experience: I didn't use the laptop much over the summer, but came back to it this week. Naturally, I used APT to upgrade the 22.04 software components to the latest and greatest -- and the instability returned as the the kernel was updated to 6.8. Typically browsing in Chrome, at some random point one tab would freeze, then Chrome would freeze, then other elements of the Gnome desktop would freeze, then the mouse and keyboard would freeze. Since the laptop was still relatively new to me, I restored the Windows 11 with SupportAssist to determine whether there could be hardware issues and experienced no freezes. For now, I've reconfigured dual-boot with Ubuntu Desktop 22.04.4 with the 6.5.0-18-generic kernel and Nouveau, which seems stable this morning so far. I'm concerned that updating the operating system (kernel specifically) or installing a proprietary nVidia driver will re-introduce instability. This G15 5530 model includes an i5-13450HX processor, nVidia RTX 4050 6GB, AX201 wireless, 16GB of RAM. Wondering if any specific later versions of the kernel would resolve this issue based on the experiences of others, or whether certain versions of the graphics driver have been found to be more stable than others with the 4050 card. I'm happy to provide more specific hardware information or logs, and do take some troubleshooting measures -- although my goal is to eventually have a stable system for work. Please note others have reported this issue in Dell forums and tried different things with variable success, but the most stable option seems to be 6.5 kernel with Nouveau for now. https://www.dell.com/community/en/conversations/linux- general/dell-g15-5530-ubuntu-2204-lts-random- crash/66c5bd7796bc9473fe644b66 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2083940/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
