I have a similar problem to the other black screen issues that I've seen recently, so maybe related. I wasn't able to start my Ubuntu 14.04 system through crouton so I updated to the newist version of crouton. Now crouton does seem to start, but when it does I get a solid black screen. <ctrl> + <alt> + <F1> does get me back to Crome OS. The output from the shell at that stace is attached below. Interestingly if I go back to Ubuntu with <ctrl> + <alt> + <F2> and then <ctrl> + <alt> + <F3> sometimes, but not always and not last time I tried it, I see the desktop flash up for maybe a fifth of a second before the screen goes black again.\r\n\r\nOutput below:\r\nchronos@localhost / $ sudo startxfce4\r\nEnter encryption passphrase for ogog: \r\nEntering /mnt/stateful_partition/crouton/chroots/ogog...\r\n/usr/bin/startxfce4: Starting X server\r\n\r\n\r\nX.Org X Server 1.15.1\r\nRelease Date: 2014-04-13\r\nX Protocol Version 11, Revision 0\r\nBuild Operating System: Linux 3.2.0-76-generic x86_64 Ubuntu\r\nCurrent Operating System: Linux localhost 3.4.0 #1 SMP Mon Apr 27 08:43:45 PDT 2015 x86_64\r\nKernel command line: cros_secure  console= loglevel=7 init=/sbin/init cros_secure oops=panic panic=-1 root=/dev/dm-1 rootwait ro dm_verity.error_behavior=3 dm_verity.max_bios=-1 dm_verity.dev_wait=1 dm=\"2 vboot none ro 1,0 2545920 bootcache PARTUUID=77a8d32c-6ae5-4744-a9c9-d38c6eb2a3fc/PARTNROFF=1 2545920 1e8c00478ff05a911b5e4259be0a666475ffc9f2 512 20000 100000, vroot none ro 1,0 2506752 verity payload=254:0 hashtree=254:0 hashstart=2506752 alg=sha1 root_hexdigest=740a5bd822ea22b024dcc580e7f21f179ca653e1 salt=fa98b29a09fde12851119d11379e8ef74a4487202d5c8e29ac229196214f54e7\" noinitrd vt.global_cursor_default=0 kern_guid=77a8d32c-6ae5-4744-a9c9-d38c6eb2a3fc add_efi_memmap boot=local noresume noswap i915.modeset=1 tpm_tis.force=1 tpm_tis.interrupts=0 nmi_watchdog=panic,lapic iTCO_vendor_support.vendorsupport=3  \r\nBuild Date: 12 February 2015  02:49:29PM\r\nxorg-server 2:1.15.1-0ubuntu2.7 (For technical support please see http://www.ubuntu.com/support) \r\nCurrent version of pixman: 0.30.2\r\n        Before reporting problems, check http://wiki.x.org\r\n        to make sure that you have the latest version.\r\nMarkers: (--) probed, (**) from config file, (==) default setting,\r\n        (++) from command line, (!!) notice, (II) informational,\r\n        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.\r\n(==) Log file: \"/var/log/Xorg.1.log\", Time: Fri May  8 13:20:26 2015\r\n(==) Using system config directory \"/usr/share/X11/xorg.conf.d\"\r\nInitializing built-in extension Generic Event Extension\r\nInitializing built-in extension SHAPE\r\nInitializing built-in extension MIT-SHM\r\nInitializing built-in extension XInputExtension\r\nInitializing built-in extension XTEST\r\nInitializing built-in extension BIG-REQUESTS\r\nInitializing built-in extension SYNC\r\nInitializing built-in extension XKEYBOARD\r\nInitializing built-in extension XC-MISC\r\nInitializing built-in extension SECURITY\r\nInitializing built-in extension XINERAMA\r\nInitializing built-in extension XFIXES\r\nInitializing built-in extension RENDER\r\nInitializing built-in extension RANDR\r\nInitializing built-in extension COMPOSITE\r\nInitializing built-in extension DAMAGE\r\nInitializing built-in extension MIT-SCREEN-SAVER\r\nInitializing built-in extension DOUBLE-BUFFER\r\nInitializing built-in extension RECORD\r\nInitializing built-in extension DPMS\r\nInitializing built-in extension Present\r\nInitializing built-in extension DRI3\r\nInitializing built-in extension X-Resource\r\nInitializing built-in extension XVideo\r\nInitializing built-in extension XVideo-MotionCompensation\r\nInitializing built-in extension SELinux\r\nInitializing built-in extension XFree86-VidModeExtension\r\nInitializing built-in extension XFree86-DGA\r\nInitializing built-in extension XFree86-DRI\r\nInitializing built-in extension DRI2\r\nLoading extension GLX\r\nxf86: found device 1\r\nxf86: found device 1\r\ncrouton: version 1-20150503215233~master:75fb08cb\r\nrelease: trusty\r\narchitecture: amd64\r\nxmethod: xorg\r\ntargets: xfce\r\nhost: version 6812.83.0 (Official Build) stable-channel parrot \r\nkernel: Linux localhost 3.4.0 #1 SMP Mon Apr 27 08:43:45 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux\r\nfreon: no\r\n/usr/bin/xbindkeys_autostart: line 24: CONF: unbound variable\r\n\r\n(polkit-gnome-authentication-agent-1:461): GLib-CRITICAL **: g_variant_new_string: assertion 'string != NULL' failed\r\n\r\n(polkit-gnome-authentication-agent-1:461): polkit-gnome-1-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files\r\n\r\n** (wrapper-1.0:478): WARNING **: Binding 'XF86AudioLowerVolume' failed!\r\n\r\n** (wrapper-1.0:478): WARNING **: Binding 'XF86AudioRaiseVolume' failed!\r\n\r\n** (wrapper-1.0:478): WARNING **: Binding 'XF86AudioMute' failed!\r\n\r\n(process:485): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed\r\n(II) AIGLX: Suspending AIGLX clients for VT switch\r\n\r\n"}}
