I tried to restore the desktop environment by typing from a virtual console:
sudo apt-get purge nvidia* sudo apt-get install nvidia-331 nvidia-prime Since then, I'm able to login into lightdm only by booting in failsafe mode at grub menu, but one odd thing is the lame nvidia-settings window shown in the attached picture. Also, the file /etc/X11/xorg.conf is now missing. I also tried to select the intel card with the command: sudo prime-select intel but then I get plenty of errors in kernel.log: Sep 17 21:08:24 Work kernel: [ 60.878559] ------------[ cut here ]------------ Sep 17 21:08:24 Work kernel: [ 60.878591] WARNING: CPU: 5 PID: 198 at /build/buildd/linux-3.13.0/drivers/gpu/drm/i915/intel_pm.c:5873 i915_release_power_well+0x5a/0x60 [i915]() Sep 17 21:08:24 Work kernel: [ 60.878592] Modules linked in: pci_stub vboxpci(OX) vboxnetadp(OX) vboxnetflt(OX) vboxdrv(OX) xt_tcpudp xt_conntrack nf_conntrack_irc nf_conntrack_ftp xt_state xt_limit xt_LOG nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack iptable_filter ip_tables x_tables rfcomm bnep nls_iso8859_1 lp nvidia(POX) joydev uvcvideo hid_logitech_dj videobuf2_vmalloc videobuf2_memops videobuf2_core usbhid snd_hda_codec_hdmi hid videodev snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep snd_pcm ath3k arc4 btusb dell_wmi snd_page_alloc snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq ath9k bluetooth snd_seq_device sparse_keymap snd_timer ath9k_common ath9k_hw ppdev x86_pkg_temp_thermal ath snd mac80211 intel_powerclamp coretemp dell_laptop e1000e dcdbas cfg80211 kvm_intel mei_me kvm psmouse parport_pc parport mei ptp sdhci_pci pps_core sdhci wmi serio_raw mac_hid lpc_ich crct10dif_pclmul crc32_pclmul soundcore ghash_clmulni_intel dm_crypt i915 aesni_intel aes_x86_64 glue_helper lrw gf128mul ablk_helper cryptd i2c_algo_bit ahci drm_kms_helper libahci drm video Sep 17 21:08:24 Work kernel: [ 60.878626] CPU: 5 PID: 198 Comm: kworker/u16:4 Tainted: P W OX 3.13.0-36-generic #63-Ubuntu Sep 17 21:08:24 Work kernel: [ 60.878628] Hardware name: Dell Inc.
