regression wrong vesa video rate set.

[bbjimmy]

in hrev54590 vesa video is not working properly. /boot/home/config/settings/kernel/drivers/vesa states : mode 1280 1024 32 but the video cannot be displayed. if I chose 1024 x 768 in the boot menu I can later change to 1280 x 1024 and it works.

syslog shows:

KERN: 1152x864@75Hz (id=20337)
KERN: 1280x1024@60Hz (id=32897)
KERN: Supported VESA Video Modes:
KERN: 720x400@70Hz
KERN: 640x480@60Hz
KERN: 640x480@75Hz
KERN: 800x600@60Hz
KERN: 800x600@75Hz
KERN: 1024x768@60Hz
KERN: 1024x768@75Hz
KERN: 1280x1024@75Hz
KERN: Additional Video Mode (1280x1024@60Hz):

My monitor needs 1280x1024@60Hz and assume it sets to 1280x1024@75Hz

It last worked ok in hrev54579

Does it break the boot screen as well or only when app_server starts?

A complete syslog of both the working and non-working versions could be useful, since the list of VESA modes didn't change and the VESA driver also didn't change in that range, the problem is possibly in app_server,either ​https://git.haiku-os.org/haiku/commit/?id=8b2b30105941e16ea895873a7248914888d12b12 or ​https://git.haiku-os.org/haiku/commit/?id=6fd227430680ddab9eecbc0747c34338e04ce3b7

showing bad video mode

syslog.54579.txt is probably useless. Maybe attach syslog.old?

In the syslog for the new revision there are two boot attempts, one with 1024x768 and the other with 1280x1024.

In both cases I see that the resolution is initially 1024x768:

1273	KERN:  0x118: 1024 x 768 x 32 (a = 155, mem = 6, phy = e0000000, p = 1, b = 1)
1274	KERN:   mask: r: 8 16 g: 8 8 b: 8 0 dcmi: 0
1287	KERN: Using mode 0x118

and it is switched (or not switched) a bit later:

1379	KERN: load kernel kernel_x86...
1380	KERN: video mode: 1280x1024x32

I don't know if this is normal or not?
