As you can see, LVDS is primary output now. You're right. My recommendations are based on my experience of solving such artefact for an Amd-690G based PC. It has an S-VIDEO output instead of LVDS, and the kernel parameter "radeon.tv=0" solves that problem. And that artefact appears in various Ubuntu-based Linux distributions, not just in Bodhi. So I guess that Moksha is not the cause. As a last attempt in your case I recommend to disable all video outputs except LVDS: video=VGA-0:d video=HDMI-0:d video=LVDS:1280x800@59.91eI hope that "disabled" in this case means the initial state of the outputs, and when you connect a projector to the HDMI output, it will be enabled again. If that doesn't help, you should dig in a different direction. |

Thanks, I will try it this evening!
Regarding other distros - now that you've mentioned IT I think you may be right. I've tried dozens of distros on this notebook, however, I've never tried specifically ubuntu-based ones. There were many debian-based ones, but it seems it is not the same after all...

video=VGA-0:d video=HDMI-0:d video=LVDS:1280x800@59.91eSo, I've tried it^ It's the same - normal reboot and power on with artifacts. By the way, I haven't mentioned it before, but with any option in this thread artifacts look a bit differently - there are much less "grains". Not sure if this is relevant.. I still cannot understand why reboot is working normally though.. |

I still cannot understand why reboot is working normally though.. I'm sorry. Unfortunately, I don't know what to do with this artifact. The Radeon driver has too many features ( www.x.org/wiki/RadeonFeature/, wiki.archlinux.org/title/ATI) and I'm confused what the option can help you. And maybe this is not driver issue but some other part of the Bodhi Linux or specific hardware feature... |

Thanks. I've tried tons of different radeon tweaks from this wiki, unfortunately, with no results. At least I found out that dpm is disabled by default for the GPUs such as mine, so I've enabled it, I believe it should be a good thing  |
