Saya menjalankan Ubuntu 16.04 LTS dengan driver NVIDIA 361 yang diinstal secara manual. Setelah memutakhirkan driver ke v367, saya sekarang terkunci dari Unity dengan loop masuk dengan kesalahan berikut di .xsession-errors :
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 3 (X_GLXCreateContext)
Value in failed request: 0x0
Serial number of failed request: 32
Current serial number in output stream: 33
openConnection: connect: No such file or directory
cannot connect to brltty at :0
Saya juga menemukan ini di Xorg log:

Terkait:Tampilkan dialog saat masuk (skrip bash)?
Saya telah mencoba menurunkan versi ke v364 dan kemudian kembali ke v361 tetapi tidak berhasil
Saya telah mencoba membersihkan xserver-xorg, xserver-xorg-core, nvidia*, lightdm tetapi tidak berhasil
Saya telah mencoba menginstal ulang ubuntu-desktop tidak berhasil
Pemformatan ulang dan penginstalan ulang yang lengkap akan sangat mengganggu dan saya ingin menghindarinya dengan cara apa pun.
Pesan kesalahan di .xsession-errors selalu tetap sama. Bagaimana saya bisa membersihkan / memulihkan / mengatur ulang pengaturan dan/atau paket dan/atau perpustakaan saya ke keadaan normal tanpa memformat ulang dan menginstal ulang sepenuhnya?
Jawaban yang Diterima:
Menambahkan +iglx ke xserver-command di /usr/share/lightdm/lightdm.conf.d/50-xserver-command.conf .
[SeatDefaults]
# Dump core
xserver-command=X -core +iglx
Setelah itu Anda reboot atau Ctrl-Alt-F1, login, dan sudo service lightdm restart .
Bekerja seperti pesona
