前段時間,我嘗試在我的 Linux Mint 18.2 Sonya 上安裝 tensorflow-gpu,但可能在安裝過程中損壞了某些東西。我在啟動時遇到了黑屏。為了解決這個問題,我編輯了/etc/default/grub
:GRUB_CMDLINE_LINUX="i915.modeset=0"
我使用 i915 參數,因為我有一個英特爾主機板(我相信)。
現在我喚醒電腦後出現黑畫面。我在網路上找到的許多解決方案都需要更改GRUB_CMDLINE_LINUX
參數,但由於我已經必須編輯此內容,所以我認為這與更改 i915 參數無關。
你知道如何解決這個問題嗎?謝謝 !
編輯:如果我刪除i915.modeset=0
,我會啟動到黑屏。這就是為什麼我首先添加了這個參數,但它只能解決啟動時黑屏的問題。在確保 Ctrl+Alt+Backspace 確實已啟動並登出後,我嘗試在「黑屏」時使用它,但它也無法解決問題。感謝@terdon 提出的這些修復建議!

我有一個類似的問題,我在各種機器和系統上都遇到過這個問題。我一直無法找到其根本原因,但作為解決方法,我為xrandr
設定螢幕的命令分配了鍵盤快捷鍵。這裡可能值得一試。
透過查看以下輸出找出目前的螢幕設定
xrandr

我實際上有 3 個活動螢幕,所以我的輸出有點複雜。這是單一螢幕設定的樣子:
$ xrandr Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 8192 x 8192 eDP-1 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 310mm x 174mm 2560x1440 60.00*+ 59.99 59.99 59.96 59.95 1920x1440 60.00 1856x1392 60.01 1792x1344 60.01 2048x1152 59.99 59.98 59.90 59.91 1920x1200 59.88 59.95 1920x1080 60.01 59.97 59.96 59.93 1600x1200 60.00 1680x1050 59.95 59.88 1400x1050 59.98 1600x900 59.99 59.94 59.95 59.82 1280x1024 60.02 1400x900 59.96 59.88 1280x960 60.00 1440x810 60.00 59.97 1368x768 59.88 59.85 1280x800 59.99 59.97 59.81 59.91 1280x720 60.00 59.99 59.86 59.74 1024x768 60.04 60.00 960x720 60.00 928x696 60.05 896x672 60.01 1024x576 59.95 59.96 59.90 59.82 960x600 59.93 60.00 960x540 59.96 59.99 59.63 59.82 800x600 60.00 60.32 56.25 840x525 60.01 59.88 864x486 59.92 59.57 700x525 59.98 800x450 59.95 59.82 640x512 60.02 700x450 59.96 59.88 640x480 60.00 59.94 720x405 59.51 58.99 684x384 59.88 59.85 640x400 59.88 59.98 640x360 59.86 59.83 59.84 59.32 512x384 60.00 512x288 60.00 59.92 480x270 59.63 59.82 400x300 60.32 56.34 432x243 59.92 59.57 320x240 60.05 360x202 59.51 59.13 320x180 59.84 59.32 DP-1 disconnected (normal left inverted right x axis y axis) HDMI-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) HDMI-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) HDMI-3 disconnected (normal left inverted right x axis y axis) DP-3-1 disconnected (normal left inverted right x axis y axis) DP-3-2 disconnected (normal left inverted right x axis y axis) DP-3-3 disconnected (normal left inverted right x axis y axis)
根據從 獲得的輸出
xrandr
,您可以建立一個命令來複製目前的設定。因此,為了獲得我的三個螢幕,我將使用:xrandr --output eDP-1 --mode 2560x1440 --output DP-3-2 --auto --left-of eDP-1 --primary --output DP-3-3 --left-of DP-3-2 --auto
對於單一螢幕,它將是:
xrandr --output eDP-1 --mode 2560x1440 --primary
或甚至只是:
xrandr --output eDP-1 --auto
這會將我的筆記型電腦的螢幕 ( ) 設定
eDP-1
在最右側,將另外兩個螢幕設置在其左側。嘗試xrandr
並獲取適合您的命令。請注意,您的系統上的螢幕名稱會有所不同,您需要弄清楚哪個是哪個。獲得正確的
xrandr
命令後,為其設定桌面捷徑。例如,在 Cinnamon 上,我可以透過前往「首選項」=>「鍵盤」=>「捷徑」=>「自訂捷徑」來執行此操作:
正如您在圖片中看到的,我已經指定了快捷鍵Super+ 3(“Super”是“Windows 鍵”)。因此,如果我的筆記型電腦的螢幕在掛起後無法喚醒,我只需點擊快捷方式即可刷新螢幕,從而有效地將其喚醒。
