debian11突然提示硬盘空间已满，文件管理器查看，剩余已经是0；
重启，结果看启动过程没问题，但最后屏幕是黑屏，按开关机按钮，屏幕会显示关机过程，并正常关机。
用启动U盘(live)启动后，删除系统上大约10G文件，然后系统可以正常启动。
我的问题是，我查到log文件夹有三个25.7G的东西，这东西可以删除不？我怀疑就是它的问题，截图如下：
还有就是，我碰到的这个情况，是常见问题么？我是第一次遇到~
ps:
用启动U盘启动电脑时，主板bios的启动项无法选择U盘，好像U盘没插入一样；并且，启动项由默认的5个变为3个。我电脑上有一个备用的windows系统，启动到win后再关机重启到bios，发现3个启动项恢复为5个，可以选择U盘启动。(那个win系统最后一次使用，大概是三个月前；之后没再用过)
不清楚是debian系统问题造成的主板bios问题，还是主板问题造成的debian系统问题，比较奇怪。
应该是可以删除的。不过，系统的日志大小是有上限的，不会无限制地增长，你这占用量有点太多了。
刚刚看了下我系统里的/var/log文件夹，只占了 3G 的空间。
以前应该是没有这么多(具体多少没注意过，回头注意一下)，最近系统不关机而是经常性人为进入休眠，不知道有没有关系～
大多数时间，我会保持根目录所在的硬盘有至少一半的空间是空闲，偶尔占用超过一半，也是临时性，马上就会删除~
系统所有目录都在一个分区中，包括home目录，仅swap和/boot/efi是另外的分区。
你这个日志文件这么大，里面很可能有很多重复的日志，你可以看看有没有报错什么的，也许能找到问题。
对于大文件，直接打开可能会爆内存，可以用sudo tail -n 10000 /var/log/message查看最后 10000 行。
根据截图来看，那三个大的日志文件是最近一个星期生成的。
我看日期是今天，不知道是不是今天一次性生成，还是累积生成。
10000行log文件有点大，是不是有什么类似图床的地方可以贴上去？
你自己找找啊，把那些重复的错误日志发一份出来就行了。
下面这一段重复了大概25次：

没看出来是什么问题，等大佬来看。
你粘贴出来的日志段应该描述了gdm的启动过程，不过是加载了若干模块，里面有可见的一些问题：
应该是xkbcomp的错误，键盘初始化失败导致X服务器崩溃，直接导致了黑屏与日志的无限循环。这就是磁盘空间不足的问题，我从ArchWiki找到：
遇到“X failed to start : Keyboard initialization failed”。 如果您的硬盘已满，startx将失败。
/var/log/Xorg.0.log的末尾会是…
在/分区上腾出一些可用空间，X才能启动。
可能就是日志导致的。单纯X服务器的日志，尽管一万行大小应该不会太大，或许是以前积累下来的/其它问题。你可以先用Live CD，用一些查看日志的工具看一看这几个文件。
在确定并且向开发者报告之前，最好不要清理，里面可能包含很多有用的信息。
因为需要使用，所以我已经删除了~
以后有类似的，我备份一下再删除~
怎么这么大的日志文件，而且涉及 user.log，是被暴力破解程序盯上了么？
你这么说，让我想到去年有一段时间，键盘输入总是异常，感觉就像是有程序在记录键盘输入；那段时间我在主机上安装了很多非官方仓库的东西，其中多数是使用pip安装~
有什么简单安全措施能防范么？
我有点后悔删除log文件了~
最简单的防范措施就是别从不可靠的来源安装软件。
这个我明白~
不过，因为必须要运行一些程序，所以，我搞了个虚拟机显卡passthrough，让程序在虚拟机里运行~
今天又出现了一次，我没有重启系统，直接删除三个文件，但之后系统已经无法在硬盘上正常写入新文件。我使用ls -Th命令查看，也显示磁盘是满的状态。
然后重启系统，恢复正常～
文件还被某进程使用，所以空间不会释放。
那三个大文件有留下来的必要么？我的意思是，如果留下来能够分析出系统哪里出问题的话，那我下一次就把文件移动到别的地方保存一下，留着分析用。
能。其实你可以压缩一下，应该能省很多空间。
好的~
