Hi,
I am an undergraduate physics student who is new to ROOT and could use some help. After going through the ROOT installation, it seems that I have run into a problem and do not have any graphical output. I am able to run ROOT and the splashscreen even appears for a few seconds when I run it. However, when I try opening a file using TBrowser or TFile, this is what I get:
root [0] new TBrowser
(class TBrowser*)0x8e907a8
root [1] TFile * 0file = TFile::Open(“run-1202-00-mona.root”)
Fatal in TVirtualStreamerInfo::Factory: Cannot find the plugin handler for TVirtualStreamerInfo! However $ROOTSYS/etc/plugins/TVirtualStreamerInfo is accessible, Check the content of this directory!

Also, when I did the build commands, it tells me that libx11 is not installed even though it actually is. This is what I get:

libx11-dev is already the newest version.

I’m running Ubuntu 12.04 under a Oracle VM VirtualBox and have the latest version of ROOT. If anyone knows how to fix this problem, I’d greatly appreciate any help.
Thanks
