播放有声视频时随机冻结

当我播放带声音的视频时，计算机经常会立即冻结，但如果我播放不带声音的视频，则一切正常。我使用的是 NVIDIA GeForce GTX 650、8gb 内存、Intel(R) Core(TM) i5-4440 CPU @ 3.10GHz。

这是来自 journalctl -b-1 的日志

据我所知，Xid (PCI:0000:01:00): 79, pid=1769，GPU 已从总线上掉下来，可能是由多种原因造成的。如能得到任何帮助，我们将不胜感激

您的 BIOS 非常旧，需要先更新。如果这不能解决问题，我们可以进一步排除故障。

Gigabyte Technology Co., Ltd. H81M-DS2, BIOS FC 01/20/2014

此主板有 5 个修订版本，我怀疑您使用的是 2.0 修订版本，因此 BIOS 更新页面是这里。除其他修复外，此修复还修复了“支持新的第四代英特尔酷睿处理器”，这就是您所拥有的...英特尔(R) 酷睿(TM) i5-4440 CPU。

笔记：确认您有 2.0 版主板

笔记：更新 BIOS 前请做好备份

更新＃1：

在里面terminal...

我们将您的 /swapfile 从 2G 增加到 4G。

sudo swapoff -a           # turn off swap
head -c 4G /dev/zero | sudo tee /swapfile  # create a new /swapfile
sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 8G RAM and 4G swap

sudo -H gedit /etc/fstab使用或编辑 /etc/fstab sudo pico /etc/fstab。

确认 /etc/fstab 中的 /swapfile 行...并确认没有其他“swap”行存在。

/swapfile  none  swap  sw  0  0

reboot                    # reboot and verify operation
