I recently installed Debian Wheezy 7.6 in my laptop which has 4GB nVidia graphics card. By default, on login it boots into gnome classic mode and reports gnome 3 failed to load. Also, sometimes the mouse pointer is not consistent (goes invisible while scrolling and clicking).This is the output of .xsession-errors:/etc/gdm3/Xsession: Beginning session setup...localuser:a12 being added to access control listopenConnection: connect: No such file or directorycannot connect to brltty at :0gnome-keyring-daemon: insufficient process capabilities, unsecure memory might get usedgnome-keyring-daemon: insufficient process capabilities, unsecure memory might get usedgnome-keyring-daemon: insufficient process capabilities, unsecure memory might get usedgnome-keyring-daemon: insufficient process capabilities, unsecure memory might get usedGNOME_KEYRING_CONTROL=/home/a12/.cache/keyring-VJMq1wGNOME_KEYRING_CONTROL=/home/a12/.cache/keyring-VJMq1wSSH_AUTH_SOCK=/home/a12/.cache/keyring-VJMq1w/sshGNOME_KEYRING_CONTROL=/home/a12/.cache/keyring-VJMq1wSSH_AUTH_SOCK=/home/a12/.cache/keyring-VJMq1w/sshGPG_AGENT_INFO=/home/a12/.cache/keyring-VJMq1w/gpg:0:1GNOME_KEYRING_CONTROL=/home/a12/.cache/keyring-VJMq1wSSH_AUTH_SOCK=/home/a12/.cache/keyring-VJMq1w/ssh(gnome-settings-daemon:16895): color-plugin-WARNING **: failed to get edid: unable to get EDID for output(gnome-settings-daemon:16895): color-plugin-WARNING **: unable to get EDID for xrandr-default: unable to get EDID for output(gnome-settings-daemon:16895): color-plugin-WARNING **: failed to reset xrandr-default gamma tables: gamma size is zero(gnome-panel:16921): Gtk-CRITICAL **: gtk_accelerator_parse_with_keycode: assertion `accelerator != NULL' failed** (gnome-panel:16921): WARNING **: Unable to parse mouse modifier '(null)'Initializing tracker-store...vmware-user: could not open /proc/fs/vmblock/devTracker-Message: Setting up monitor for changes to config file:'/home/a12/.config/tracker/tracker-store.cfg'Tracker-Message: Setting up monitor for changes to config file:'/home/a12/.config/tracker/tracker-store.cfg'Starting log:  File:'/home/a12/.local/share/tracker/tracker-store.log'Initializing tracker-miner-fs...Tracker-Message: Setting up monitor for changes to config file:'/home/a12/.config/tracker/tracker-miner-fs.cfg'Starting log:  File:'/home/a12/.local/share/tracker/tracker-miner-fs.log'** (gnome-screensaver:16959): WARNING **: Config key not handled: disable-application-handlers** (gnome-screensaver:16959): WARNING **: Config key not handled: disable-command-line** (gnome-screensaver:16959): WARNING **: Config key not handled: disable-log-out** (gnome-screensaver:16959): WARNING **: Config key not handled: disable-print-setup** (gnome-screensaver:16959): WARNING **: Config key not handled: disable-printing** (gnome-screensaver:16959): WARNING **: Config key not handled: disable-save-to-disk(gnome-panel:16921): Gtk-CRITICAL **: gtk_accelerator_parse_with_keycode: assertion `accelerator != NULL' failed** (gnome-panel:16921): WARNING **: Unable to parse mouse modifier '(null)'** Message: applet now removed from the notification area(gnome-panel:16921): GLib-GObject-WARNING **: /tmp/buildd/glib2.0-2.33.12+really2.32.4/./gobject/gsignal.c:2459: signal `size_request' is invalid for instance `0x230b6c0'** Message: applet now embedded in the notification areaInitializing nautilus-gdu extension(gnome-settings-daemon:16895): updates-plugin-WARNING **: Failed to get symlink: Error when getting information for file '/run/udev/firmware-missing/ar3k/ramps_0x31010000_40.dfu': No such file or directoryShutting down nautilus-gdu extensionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selectionWindow manager warning: Log level 16: Error converting selection(gnome-settings-daemon:16895): PackageKit-WARNING **: couldn't parse execption 'GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._pk_5ftransaction_5ferror.Code4: GetDistroUpgrades not supported by backend', please report(gnome-settings-daemon:16895): updates-plugin-WARNING **: failed to get upgrades: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._pk_5ftransaction_5ferror.Code4: GetDistroUpgrades not supported by backendI've no idea what these are. I googled and cannot find a solution to it. Was it due to my graphics card? If so how can I resolve them?UPDATE: I really don't want gnome-3 but the classic mode. So, it is suffice for the classic mode to be perfect.
