我有：

mona@pascal:~$ cat /etc/default/sysstat
#
# Default settings for /etc/init.d/sysstat, /etc/cron.d/sysstat
# and /etc/cron.daily/sysstat files
#

# Should sadc collect system activity informations? Valid values
# are "true" and "false". Please do not put other values, they
# will be overwritten by debconf!
ENABLED="true"

进而：

mona@pascal:~$ sudo sar -d
Cannot open /var/log/sysstat/sa20: No such file or directory
Please check if data collecting is enabled in /etc/default/sysstat

你能建议修复吗？

我通过大学许可证安装了 MATLAB 2020，我注意到字体特别小。此外，在 Ubuntu 启动时，会为我的密码打开一个 GUI，它也非常小。我在 Ubuntu 20.04 中使用的其他 GUI 窗口没有这个问题。原因是什么，我该如何解决？
