Guest Display Stuck in Resize Mode

[wsanders]

I know there are shortcut key for this, but they are "Host-something" in Windows and seem broken. There is no "Host" key in windows, first.

I've tried Alt-G, Ctrl-G, Windows-G. Fn-G, and all the shift variations of those, and none work. Is there a secret to getting shortcut keys to work?

The host key is usually the right ctrl unless you changed it. You can also see or change this in the preference section.

[wsanders]

Thanks for the quick response - I now see the host key mapping at the top, mine's the default Right-Ctrl. But none of the shortcuts work.

I destroyed this VM anyway by trying to rotate the display, so I'm going to just reinstall, will be faster.

I am all set, here is brief Fedora 20 on VB on Windows 7 that may be useful for n00bs:

- Install Virtualbox
- Create a VM with the maximum recommended ("green") amount of Video RAM configured
- Install gcc and kernel-devel packages if you need them (eg the Live CD only installs a basic OS, like you would send to your Grandmother for a web appliance.)
- Reboot and set up c:\windows\Program Files\Oracle\VBoxGuestAdditions.iso as a virtual CDROM, then mount the virtual cdrom on the guest.
- Open a terminal window, sudo to root, and run ./VBoxLinuxAdditions.run as root.
- Power cycle the guest (rebooting is probably sufficient but for a guest it takes the same amount of time.)
- Maximize the desktop to full screen with right-Ctrl-Backspace

Small disclaimer here:

- Maximize the desktop to full screen with right-Ctrl-Backspace

This may be what is defined but it is not the default hot key for full screen, ( host+F ) or ( rt ctrl+F ), is.

[wsanders]

Not sure how it got set to right-Ctrl-Backspace. It's boldfaced in the settings, so I guess I must have set it somehow to the nondefault value.

Anyway, I posted my HOWTO too soon. I rebooted the guest and now the screen is going to 1600x1200 when I go to fullscreen mode. Unfortunately, my display is 1600x900, and this is not one of the native resolutions in Fedora. When I go to fullcreen, the bottom 300 px bleed off the bottom. In non-fullscreen mode, I can access the entire display with scroll bars.

I've tried hacking a special modeline with xrandr but so far no luck. I can add a modeline for 1600x900 but when I try to set the mode xrandr says "Cannot find mode".
I'd cut and paste but the clipboard doesn't work even though I have it set to "bidirectional".

[Perryg]

Did you by chance define a custom resolution previously?

[wsanders]

Nope, it just worked.

[Perryg]

With the guest in full screen post the guests log file and the guests Xorg.0.log, both as attachments.

I worked on this some more over the weekend and my guest's root (/) filesystem filled up. I resized the filesystem and that fixed the problem .... so fullscreen mode is working great.

One more thing to check if you are having mysterious problems .... thanks for all the help here.

The problem I was trying to solve was - I have a Lenovo X1 Carbon with a built-in 1600x900 13-inch display and a 1980-1080 23-inch external display, and I must run Windows. Windows cannot handle the big difference in DPI on the two screens, so type is either too small on the laptop display or two large on the external. The solution is to run two OS-es - Windows on the external display, and Fedora on the laptop panel. The Fedora fonts look a lot better than Windows on the super-high-res display, too.
