競合が発生しやすいファイルがありますmplayer。これが発生すると、セッション全体が中断され、ログインページに戻ります。
私のテストでは、
smplayer：衝突は体系的です。mplayer：衝突は体系的ではありませんが、定期的に発生します（10分の1でも再現可能と見なすことができます）。
それにもかかわらず、画像は衝突前または衝突が発生しないとわずかに歪んでしまいます。
私はDebian Jessieを使用しています：
MPlayer2 2.0-728-g2c378c7-4+b1
SMPlayer v. 14.9.0
lightdm 1.10.3-3
グラフィックカード ATI/AMD R7 240:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240]
radeon無料ドライバを使用してください。
mesaこれは10.3と13.0（バックポート）の両方で発生します。 Linux 3.16と4.9の両方に適しています。
