Seamless mode on Solaris host no longer uses the full screen width

[IanC]

Using a windows guest on a Solaris host, selecting seamless mode on a 30" screen now (since 4.3.x if I recall) doesn't use the full screen width.

Hi. What amount of Video Memory emitted for that VM?

And please attach the complete VBox.log file of such a VM session!

After installing the latest guest additions, I've lost seamless mode...

00:00:39.365851 Guest Additions capability report: (0x0 -> 0x4) seamless: no, hostWindowMapping: no, graphics: yes

What is your host resolution? The log file you attached from when seamless mode was working said that the host told the guest to switch to a resolution of 2400x1567 (I presume that is 2400x1600 minus a task bar) and the guest seems to have done that.

If seamless is still not working for you, does starting "VBoxTray" inside the guest help?

[IanC]

The host resolution is 2560x1600. From xdpyinfo:

screen #0:

dimensions: 2400x1600 pixels (824x310 millimeters) resolution: 74x131 dots per inch depths (7): 24, 1, 4, 8, 15, 16, 32 root window id: 0x4be depth of root window: 24 planes

VBoxTray is running (shows up in windows task manager.

OK, it turns out the xdpyinfo output I posted is for screen0, which is 2400x1600. The problem is I am displaying VB on screen1, which is the 2560x1600 display. The problem started when I changed graphics cards and the screen numbers were reversed.

Maybe VB should have a means of determining which screen it is displaying to on a multi-screen system?

Please reopen if still relevant with a recent VirtualBox release.
