2020-05-20 amdgpu使っててX11の画面が映らなくなったのを直して起動できましたにっき

ある日、画面が固まった。そもそも固まるとは?という感じだが音声の再生は続いておりしばらくはYouTube musicのホットEDMリストが流れていた。やんだ。電源を切った。

再起動するとなぜか画面が映らなくなった...

色々としらべたら終業時間だったので終わってご飯を食べた。

症状としては起動すると起動時のログが流れるのは見える。LUKSの暗号化解除のプロンプトも出る。解除も出来る。その後画面が真っ黒のまま、映像信号は出ていそうだけど何も動きがなく、止まる。起動するときにディスクアクセスのランプは光る。画面が消えるとディスクアクセスも止まっている。

systemd-bootを使っているのでまずは起動時にe連打してカーネルパラメータを編集する。 systemd.unit= を指定したけどtypoしてて起動できず（今ログを見て確認した）。雑に init=/bin/sh して様子を見てみる。ディスクが埋まっていることもない。 journalctl -S 2020-05-20 でログを確認する。 error とか Error でgrepしてもなかなか分からず。

ろぐは雑にはる（ぬけある）けど

Ubuntuのバグトラッカーを発見 bugs.launchpad.net

これやん、ってなって付けたしたら普通に上がるようになった

/etc/X11/xorg.conf.d/20-amdgpu.conf
Section "Device"
     Identifier "AMD"
     Driver "amdgpu"
     Option "DRI" "3"
EndSection

他 amdgpu がなくても画面出てたはずなのになんでだろう、と radeon やら vesa の設定をしらべていて1024x768環境でなんで4k出ないのか、ディスプレイのモデルを調べるコマンドは、などしらべものをしては modprobe して再起動みたいなのとか、 /etc/gdm/custom.conf で WaylandEnable=false をコメントインして起動などを何度かしていた。

疲れたが直ったのでよし。

/var/log/Xorg.0.log をもっと早めにみていれば...

systemd.unit=rescue.target と systemd.unit=multi-user.target をtypoしていなければもっと早めにsystemdの便利ログが見れたであろう
雑に /bin/sh した結果様々なログが残らなかった、 initを叩こう
Xの問題の可能性があるときはXのログを見よう
rw 忘れずに

みたいな感じかな、ぴえん.....

椅子の座り方を色々試していて、後傾にするときモニターアームがあると便利というのに気づく

こどもがモニターアームブンブンイジるので不便...こわい...

椅子、肌触りはいいし見た目もいいけど座面の横のカーブが想像よりきつくて横向きに座れなさそう、手をぶんまわす趣味もないしアームレストついてたほうが疲れなかったかも。まあ買ってみないとわからないしかえって筋肉がつくということで。

たぶんこの椅子うねうねしすぎてリプロダクト品が出ることはないんじゃないかしら、そこは「安いのでよかったかな」とはならないのでいい、高いのしかない。

持ち家じゃないのにこんな高い椅子は不釣り合いでは、という気がしなくも無いがまあ気にせず。

座高が高いので多分もう少し年齢がいくともっと便利と感じることが多そう。今あるリビングの椅子は座面が低いのでしんどい。

高いスマホ数年しか使わないのに比べたら多分使うはずだし中古の値段も全然崩れてないので、その点はいいかもしれない。

spartial chatを試しに使ってみた。楽しい。Okinawa.rbしたい。

学生のときに作った口座の送金限度額が学生らしい金額になっていてたまに困るので変更の届け出をしてきた。あまり困らない程度には送金できる。

モバイルバッテリーが膨らんできていて捨てたいけど那覇市は回収してくれない。捨てる方法を探している。
