I've used (previously) Sugar (a long time ago, when I was a smol kiddo), and Ubuntu. I've tried to get Red Hat Fedora and Slackware running on a (god awful) laptop from the pre-2000 era of tech, but the CD-R's I've used never really "worked" on it. For example, syslinux didn't work on 2 of the discs, and the BIOS is trashed on the laptop, so yeah.
I can't really use it ("it" being most linux distros) because it doesn't have a (mind you, "user friendly") way of installing the *correct* drivers for older (pre-GCN) Radeon GPU's, and I'm too lazy to kernel-compile a radeon driver.
I've had issues with AMD GPUs before and most of the time I end up using one of these; Solus, Sabayon, Korora, Manjaro, or Chakra. Those seem to be the best for difficult GPU's.
