** Description changed:

- Potentially a duplicate of Bug #1322413 (but different architecture and
- video card)
- 
  Graphics card is  Radeon HD 6770. X.Org drivers. Clean install, video
  works but color depth is < 24bpp. I tried adding DefaultDepth parameter
- on xorg.conf.
+ on xorg.conf. Secondary card is integrated on the motherboard (Intel
+ E3-1200 chipset). Delivers 24bpp right away, no  tinkering required.
