i cannot access ubuntu system on my pc,
the error message: "the system is running in low graphics mode"
and i tried some commands i searched from internet.
i found out a problems seems there is no available disk space.
i used "df" and "du" commands to check, the results are as follow:
du -j --max-depth=1 23G ./home 3.3G ./usr ...... 28G
df -Th filesystem Type size used available use% mounted on /dev/sda5 ext4 68G 68G 0 100% /
how would i clean up the system for more memories?
thanks in advance for any helps.
