I've been attempting to set up Linux for the first time. I've experimented with multiple distros recently, but each encountered difficulties. Finally, Ubuntu worked after I switched to BIOS mode and set the "nomodeset" option. This indicates it was installed in BIOS, not UEFI. Now I'm facing several problems during installation. When starting up, I see black and white stripes unless I enter recovery mode. It's functioning normally otherwise, except for video playback on the PC. In recovery mode, the Intel Graphics drivers appear to be faulty, causing choppy video that relies heavily on CPU performance. This suggests a potential driver issue tied to the recovery setup. I'm planning to try a UEFI installation next. My goal is to enable "nomodeset" while booting from the Live USB in UEFI mode, as I can only manage it in BIOS. Any guidance would be greatly appreciated. Thanks, Alex.

Edit GRUB configuration file and include "nomodeset" in GRUB_CMDLINE_LINUX_DEFAULT. Run grub-mkconfig -o /boot/grub/grub.cfg to apply changes.

This should function from the Live USB.

It seems you're confirming the installation was already completed. From the live USB, pressing E when reaching the grub menu should allow you to add 'nomodeset' under the "linux" option as described.

Thanks for the advice. I think I've found my issue. When opening GRUB, I only get the command line while in UEFI mode. After further investigation, there is something wrong with the GRUB when using the drive in USB mode. I'm going to try recreating the bootable USB now to see if I can fix the issue.

Enable nomodeset to ensure compatibility with certain hardware. The GPU you have is not specified in this context.

Intel built-in for Pentium N3540 is creating several issues. It finally started booting in UEFI mode, and I installed Ubuntu there instead of using BIOS. However, my network adapter isn’t functioning properly, even though it was connected via the Live USB. I don’t have any graphics drivers installed, but I still need internet access to get them working, so fixing the network adapter is my top concern. Each fix I make seems to bring up another challenge during this setup.

I acknowledge your points, though the circumstances don’t align with my expectations. Intel offers excellent Linux support, which is common. The UEFI setup might be standard for your system. Regarding the network card, Intel and Qualcomm provide strong built-in functionality, while Broadcom offers decent support but requires compilation from source. Realtek generally has poor performance and battery life, unless you compile beta drivers yourself.

Sorry about that, I was preparing for exams. Now I'm back. Broadcom wireless and Realtek ethernet both function when installed in BIOS or from a Live USB, but not with UEFI. I don’t understand why it doesn’t work as expected. It’s really annoying. I’m restarting now and planning a fresh install in UEFI to test the network cards. I’ve followed all the online suggestions.

I'm sorry for the delay, this seems quite unusual. Could you tell me what laptop you're using? There might be a firmware issue. On the Linux side, the Ethernet connection should function (though not at expected speeds because Realtek's driver depends too much on CPU power, and your processor is relatively weak). The Broadcom chip might need closed-source firmware to work properly, which you can install by opening "Software and Repositories" (or similar) and selecting "Additional Software" under the appropriate settings. You should be able to find an option to switch to closed-source components for that chip (Broadcom doesn<|pad|>'s restrict their firmwares in Linux firmware). This will require internet access.
