I am facing this problem,and I don't know I dig into it. As I log into Ubuntu my mouse pointer get stuck. I have tried the following methods:sudo apt-get updatesudo apt-get upgradeI have also tried this:sudo apt-get install -fsudo dpkg --configure -asudo apt-get install -fAlso, lots of other methods. But none works for me. Please guide me how I can restore my pointer.I don't face this problem when I log in as a Guest user in Ubuntu, also my mouse starts moving when I attach an external USB mouse.This is output of my lsmod command     haider@ubuntu:~$ lsmod | sort     arc4                   12473  2     bcma                   25651  0     binfmt_misc            17292  1     bluetooth             158447  10 rfcomm,bnep    bnep                   17830  2     brcmsmac              540923  0     brcmutil               14675  1 brcmsmac    cfg80211              178877  2 brcmsmac,mac80211    cordic                 12518  1 brcmsmac    crc8                   12781  1 brcmsmac    dcdbas                 14098  1 dell_laptop    dell_laptop            17767  0     dell_wmi               12601  0     drm                   197641  4 i915,drm_kms_helper    drm_kms_helper         45466  1 i915    hid                    77428  1 usbhid    i2c_algo_bit           13199  1 i915    i915                  428056  8     intel_ips              17822  0     joydev                 17393  0     lp                     17455  0     mac80211              436493  1 brcmsmac    mac_hid                13077  0     mei                    36570  0     Module                  Size  Used by    parport                40930  3 parport_pc,ppdev,lp    parport_pc             32114  0     ppdev                  12849  0     psmouse                86520  0     r8169                  56396  0     rfcomm                 38139  0     serio_raw              13027  0     snd                    62218  16 snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device    snd_hda_codec         109562  3 snd_hda_codec_hdmi,snd_hda_codec_idt,snd_hda_intel    snd_hda_codec_hdmi     31775  1     snd_hda_codec_idt      60251  1     snd_hda_intel          32719  3     snd_hwdep              13276  1 snd_hda_codec    snd_page_alloc         14108  2 snd_hda_intel,snd_pcm    snd_pcm                80916  3 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec    snd_rawmidi            25424  1 snd_seq_midi    snd_seq                51592  2 snd_seq_midi,snd_seq_midi_event    snd_seq_device         14172  3 snd_seq_midi,snd_rawmidi,snd_seq    snd_seq_midi           13132  0     snd_seq_midi_event     14475  1 snd_seq_midi    snd_timer              28931  2 snd_pcm,snd_seq    soundcore              14635  1 snd    sparse_keymap          13658  1 dell_wmi    usbhid                 41937  0     uvcvideo               67203  0     video                  19115  1 i915    videodev               86588  1 uvcvideo    wmi                    18744  1 dell_wmi
