Jawaban:
Saya mencoba dari snapshot cadangan sistem saya, memungkinkan
Pre-released updates (trusty-proposed) in Software & Updates > Updates. Setelah sistem diperbarui.Saya berlari,
sudo apt-get upgradeReboot dan desktop unity kembali 100%
Saya harap ini bekerja untuk Anda semua.
PS Selama minggu frustrasi saya menemukan Timeshift yang membuat cadangan sistem Anda, tidak ada file pribadi sehingga Anda dapat kembali ke keadaan sebelumnya sebelum pembaruan dll.
Saya tidak akan pernah melakukan pembaruan sistem lagi tanpa cadangan untuk dapat kembali.

Setelah upgrade kemarin sistem saya (DELL XPS dengan grafis Intel) mendapat masalah yang sama setelah restart pagi ini.
Pertama saya memeriksa paket-paket yang diperbarui kemarin:
Pembaruan kemarin berisi paket libgl1 * berbeda. Jadi saya mulai memeriksa konten mereka dan paket libgl1-mesa-dri: amd64 adalah yang saya cari:
Objek bersama yang rusak i965_dri.so adalah bagian dari paket ini. Saya memeriksa versi yang lebih lama dari paket itu dengan:
dan memutuskan untuk menggunakan versi 10.1.0-4ubuntu5.
PERINGATAN: Jangan mulai dengan perintah saya sampai Anda membaca sampai selesai !!!
Ini mengarah ke daftar panjang paket yang perlu saya bersihkan:
TETAPI jika Anda membersihkan semua paket itu, Anda akan membersihkan beberapa paket penting lainnya , bagi saya setidaknya persatuan, libunity-core-6.0-9, sesi ubuntu, cairo-dock dan xserver-xorg yang paling penting.
Pertama saya menginstal kemudian libgl1-mesa-dri di versi yang lebih lama:
Kemudian saya menginstal ulang lib yang dibersihkan lainnya, tanpa libqt5gui5, dalam versi yang lebih lama:
Setelah itu saya menginstal paket yang hilang yang saya butuhkan:
Saya juga memutuskan untuk menggunakan versi persatuan yang lebih lama, hanya untuk memastikan. Jika Anda ingin menggunakan set versi yang lebih lama
A=7.2.0+14.04.20140423-0ubuntu1.2jika tidak hanya menghapus bagian=$Abelakang paket.Sistem saya berjalan baik lagi setelah langkah-langkah ini. Hanya gambar latar belakang tidak ada di sana dan saya perlu menginstal ulang cairo-dock, tetapi konfigurasi dock lama saya masih ada.
Saya tidak dapat menjamin bahwa ini adalah deskripsi rollback lengkap untuk sistem everyones. Mungkin ada lebih banyak paket yang hilang yang perlu diinstal ulang setelah pembersihan. Ini mungkin beberapa pengalaman untuk menemukan, apa yang hilang ... Bagi saya terutama sesi ubuntu yang hilang adalah masalah untuk ditemukan.
Xserver yang hilang juga sedikit mengganggu setelah restart karena saya tidak tahu apakah wlan bekerja pada mode pemulihan atau tidak, tetapi berfungsi dengan baik dan instalasi xserver-xorg tidak menjadi masalah.
@ Back.Slash: Apakah Anda membuka tiket untuk masalah ini di launchpad? Bagi saya itu jelas terlihat seperti bug di objek yang dibagikan.

holdpaket upgradelibgl1-mesa-drihal pertama dalam sistem ubuntu baru dan berfungsi sangat lancar.Saya juga mengalami masalah ini pada Asus Zenbook setelah peningkatan. Kemudian saya perhatikan bahwa itu hanya untuk akun utama saya di mesin, tetapi jika saya masuk dengan akun lain itu tidak masalah. Pada akhirnya ini menyelesaikannya untuk saya:
(Saya hanya menggunakan
mvjika terjadi bencana.)Reboot, dan semuanya baik-baik saja.

Memotong. Saya juga punya masalah dengan Unity setelah memperbarui dari 12,04. Meskipun gejalanya berbeda, saya percaya perbaikan yang sama juga dapat melakukannya untuk Anda:
sudo apt-get install --reinstall ubuntu-desktopIni akan menginstal ulang lingkungan desktop dengan mulus. Setelah itu Anda mungkin juga perlu memulai kembali sesi Anda dan mengatur tema kembali ke default.

Saya memiliki konfigurasi laptop yang sama, dan hal yang persis sama terjadi pada saya ketika saya memperbarui kemarin.
Saya menginstal LXDE sehingga saya masih bisa memiliki GUI untuk digunakan saat mencari solusi untuk masalah ini. Tidak menyadari bahwa GNOME masih berfungsi, jadi terima kasih untuk catatan itu.
Coba cari laporan bug ( https://bugs.launchpad.net/ubuntu/trusty ) atau mengajukan sendiri.
Saran saya yang lain adalah membeli laptop baru dan meledakkan laptop Anda saat ini, yang akan saya lakukan sekitar bulan ini karena saya mengalami cukup banyak masalah dengan mesin ini.
Saya akan mengedit posting saya jika saya menemukan solusi nyata.

Jawaban ini adalah kompilasi dari apa yang saya coba berdasarkan pada apa yang saya temukan di Stack Overflow. Saya memiliki masalah serupa dan ini bekerja pada sistem Ubuntu 15.04. Anda dapat mencobanya di versi Anda.
Periksa python2 - coba tingkatkan ke versi terbaru
Milik saya sudah diperbarui ke versi python 2.x terbaru.
Instal persatuan. (Itu entah bagaimana dihapus dan mengakibatkan bilah tugas hilang)
Coba jalankan persatuan
sudo apt-get install --reinstall python-dbusIni tidak menyelesaikan masalah. Saya masih mendapatkan kesalahan impor ketika saya menjalankan persatuan.
Ini memecahkan masalah. Ketika saya menjalankan persatuan, saya mendapatkan header saya kembali.
