I recently upgraded my dual-boot HP laptop (dv7-3060us, 17.3" display) from ubuntu 12-4 to 12-10. After the upgrade, only three (3) resolutions are available (800x600, 1024x768, and 1152x864, all 4:3 resolutions), none of which are 16:9. Everything worked properly in 12-04. The display adapter is ATI Mobility Radeon HD 4530. Does anyone have any ideas/suggestions about how to correct this problem? Thanks.
