This may be a bit of a long shot, but: according to the modes file you |
| 52 |
included, your monitor only actually supports 1600x900 at 59 Hz. Since |
| 53 |
you aren't specifying a refresh, uvesafb says in dmesg that it is using |
| 54 |
a default refresh. My guess is that means "60", rather than some smart |
| 55 |
value. Does anything different happen if you specify the full mode, |
| 56 |
e.g. 1600x900-32@59? |
| 57 |
|
| 58 |
I'm afraid if that doesn't help I'm not likely to be much good myself. |
| 59 |
But I thought seeing that 59 there was odd, and figure it might be worth |
| 60 |
a look. |
