[06:02] <furkan> mlankhorst: i've been noticing some strange checkerboarding effects with Xorg 1.17... it's very subtle, but it's there, i should take a video
[06:05] <furkan> it doesn't really bother me much (i'd take this over the text corruption bug in 1.16 any day), but i think you might find it interesting
[06:10] <furkan> it comes out surprisingly clear in the video... here it is, for everybody's viewing pleasure: https://www.dropbox.com/s/ez2v03oetppecgx/VID_20150324_020612.mp4?dl=0
[06:11] <furkan> that's just an example of how it manifests itself, but i also observe it at other times like moving or maximizing windows or whatever
[06:28] <mlankhorst> furkan: file a  bug?
[09:05] <alkisg> Hi, in LTSP we netboot clients from a single image. I would like to be able to install nvidia-current in that image, and to only have it activated in clients that actually have an nvidia graphics card.
[09:06] <alkisg> If we just blindly install nvidia-current in the image, we have a lot of issues, e.g. intel clients showing their screen upside down etc
[09:06] <alkisg> So, the way I'm thinking to implement this, is to create an nvidia-current-ltsp package, that would depend on nvidia-current, but then undo all the "update-alternatives" that nvidia.postinst does
[09:07] <alkisg> We do have multiple points in the ltsp client boot process where we can detect if a client has nvidia, and redo all the update-alternatives... E.g. in the initramfs, at init, at xorg.conf generation...
[09:08] <alkisg> Does that idea make sense? Is there anything better that we can do?
[09:10] <alkisg> Btw, I see that nvidia-304 triggers an initramfs update, but inside the new initramfs, the only new things I see are two dangling symlinks, x86_64-linux-gnu_GL.conf -> /etc/alternatives/x86_64-linux-gnu_gl_conf and nvidia-graphics-drivers.conf -> /etc/alternatives/i386-linux-gnu_nvidia_modconf
[09:10] <alkisg> Is there anything needed to be done in the initramfs?
[15:31] <alkisg> I see that debian has a different set of nvidia packages that even allow multiple version installed, maybe I could tell ltsp ubuntu users to use the debian nvidia packages instead?
[17:51] <furkan> mlankhorst: i probably will, after trying a few things to see if it can be narrowed down
