I am experiencing this strange issue with Ubuntu 20.04 where after I install it to a device, it will properly boot into the fresh install after, and continue to boot properly when restarted, but stops working after boot order is changed as it doesn’t show up as a boot option on MacBook boot options or on Windows laptops in UEFI. I’m mostly installing on MacBook Pros, and modern Ubuntu does not have this issue, but 20.04 does, and it persists on Windows laptops too. I experienced ä similar issue in the past where Ubuntu 14.04 would not show up at all or boot after installing. Are the ISOs canonical puts out for legacy versions broken?

I have multiple old MacBook Pros that have Nvidia GPUs in them, they work great, except the old ass Nvidia GPUs cause so many issues. They take 20+ seconds to wake from sleep, they make me unable to play games even though the iGPU should work because it still defaults to the discrete GPU, the nouveau drivers struggle with stuff like gnome graphical acceleration, and they lead to unnecessary battery drain. I have attempted to disable Nouveau to get it to just use the iGPU, but this creates the effect of just using it with zero drivers, no graphical acceleration of any kind, even just for desktop. There are apps for macOS that allow you to simply force the system to only use integrated, is there anything like that for Linux?

My game will constantly stutter, basically just freeze for 5-10 seconds. It happens during cutscenes too where it will freeze visually but the audio will continue and the visuals will continue where the audio is once it has unfrozen. At times it is worse than others. The game is still playable (I finished it), but I am replaying, and it is so annoying especially during cutscenes. My specs are: 15 9400, 16gb
RAM, 1080ti, Windows 7 Ultimate. I played it on hard drive originally, but it still happens on SSD after i moved it to my 600mbps ssd. How do I fix this?

I am using a 15 inch late 2013 MacBook Pro with a GT 750M on fedora. Works well, except for Nvidia related problems. It will sometimes crash my desktop environment and send me back to the login screen when streaming my screen over discord and play a video at the same time, and once or twice has tried to swap to the gpu during normal use and crashed gnome. It would be nice to disable it all together, get the thermal and battery boost, and the Iris Pro 5200 1.5gb should be able to handle video encode for streaming as well as gnome animations well.

26.04 requires 6gb ram. Has anyone tried it on 4 gb? what is the experience like? Does 26.04 actually use more ram than 24.04?

I am using 24.04 currently, and while the hardware I’m using it on isn’t the greatest (early 2010s laptops) i am experiencing a lot of slowness that I don’t on OpenSUSE when running it off of a flash drive (Sandisk Ultra Fit 128gb 400mbps). Generally, how does the performance seem on 26.04? Better than 24.04? The same? Worse?
