Ubuntu 16 04 wont wake up from suspend
Ubuntu 16 04 wont wake up from suspend
I recently installed Ubuntu 16.04 LTS Xenial Xerus on my Thinkpad E550. I honestly regretted it not just because it doesnt support AMD proprietary fglrx driver aka AMD Catalyst or AMD Radeon Software but because the suspend feature stopped working.
I initially thought that this had something to do with video drivers that I had installed on Ubuntu 15.10 which were now incompatible with 16.04. I realized that this was not the case as the issue persisted even on opensource drivers that it is compatible with.
Also on a closer observation I realized that it was not that my system was not able to wake up from suspend, but that it was not able to suspend at all. On suspending, the screen would go off but my laptop kept running, heating up and draining battery. This problem existed when I hibernate or shutdown as well.
Now the only possible reason for this is some problem in acpi which is not letting my system to suspend. Ubuntu 16.04 is shipped with kernel 4.4. A quick search on this issue on kernel 4.4 made me realize that this exists across several destros and mostly on thinkpads. So I upgraded to kernel 4.5 and the problem is resolved.
Then reboot!

Twitter Gue Ke Suspend
Twitter Gue Ke Suspend
Pagi pagi dapat kabar yang menurut gue kagak enak banget :( kenapa? yak lu liat aja gambar ini
Udah pada liat kan gambar diatas? yak terhitung sejak tadi pagi (20 september 2013) akun gue udah ga bisa di pake lagi (mudah mudahan cuma sementara). Sekarang gue ga tau harus ngapain, katanya sih suruh ngelapor ke pihak twitternya, dan ngemis ngemis supaya di balikin lagi. Hah! entah bener entah kagak, gue ikutin cara cara yang gue cari di google. Kalo balik ya sukur, Kalo ga balik maaah.......... yaudah gapapa.
Gue sih yakin, kenapa akun gua bisa di suspend, dan gue sih sadar kesalahan gue, tapi ya jahat amat twiter yah hahaha. Buat kawan kawan gue yang ngeliat tulisan ini dan ngebaca, tolong banget jangan mention twitter gue, karena percuma, mentionnya cuma bisa gue liat, dan gue ga bisa bales. Buat sementara waktu, kayaknya gue mengandalkan facebook doang nih.
Twitter itu lebih enak, lu bebas ngapain aja, bacot sepuasnya ketimbang facebook yang terlalu aneh.
Twitter gue: @dhikaus .......... semoga developernya balikin lagi akun gue... Amiiin
Dan akhirnya twitter gue pun kembali, setelah 7 JAM di suspended oleh twitter. Aneh? banget, ga sampe sehari. hahaha
