Jan 4 vivid 64 .iso still same problem, wallpaper vertical bars and hashed.
Rebooted latest update vivid.
Monitor is 1920x1080., vertical bar background. Internet windows and terminal windows fine.
Tried 1360x768. Wallpaper Vertical bars.
Tried 1280x720. Vertical bars.
Tried 1024x768. Wallpaper O.K. but figure is stretched horizontally, i.e. fat because resolution geometry 4:3 doesn't fit screen 16:9.
Switched back to 1360x768, Wallpaper now O.K. ???
Conclusion, something screwed up in the calculations for varying resolution from 1920x768 (tiny print) to legible 1360x768. Only calculation that's reliable is 1024x768, which is 4:3 does not look good on this 16:9 screen besides being too coarse.
What code does the calculations for choice of pixels for varying resolutions? lightdm? Xorg? Unity?
Sure would help if Bug #1405867 were fixed so that selecting different wallpapers actually changed the wallpaper instead of having to reboot to get different wallpaper.
Appreciate any thoughts on this situation.
