I have Windows 10 build 10166 on a very old Dell E1505 laptop with an ATI Mobility X1300 display adapter. Windows 10 didn't actually have a driver for this adapter, so I borrowed the one from Windows 7. Whenever I cold boot (shutdown -> power on), I only see a white mouse cursor on a black/blank screen instead of the login screen. I can move the mouse around, but that's about it (that I can see anyway). In this state, if I put the laptop to sleep by closing the lid, then turn it back on, the display then works correctly and I can login normally. If I boot from hibernate, then the display also works just fine. Any ideas if this is fixable?
